The True Power Of Water
Dan Kami ciptakan dari air segala sesuatu yang hidup." (Q.S. Al Anbiya:30)
Dalam kitab-kitab tafsir klasik, ayat tadi diartikan bahwa tanpa air semua akan mati kehausan. Tetapi di Jepang, Dr. Masaru Em oto dari Universitas Yokohama dengan tekun melakukan penelitian tentang perilaku air.
Air murni dari mata air di Pulau Honshu didoakan secara agama Shinto, lalu didinginkan sampai -5oC di laboratorium, lantas difoto dengan mikroskop elektron dengan kamera kecepatan tinggi. Ternyata molekul air membentuk kristal segi enam yang indah. Percobaan diulangi dengan membacakan kata, "Arigato (terima kasih dalam bahasa Jepang)" di depan botol air tadi. Kristal kembali membentuk sangat indah. Lalu dicoba dengan menghadapkan tulisan huruf Jepang, "Arigato". Kristal membentuk dengan keindahan yang sama. Selanjutnya ditunjukkan kata "setan", kristal berbentuk buruk. Diputarkan musik Symphony Mozart, kristal muncul berbentuk bunga. Ketika musik heavy metal diperdengarkan, kristal hancur.
Ketika 500 orang berkonsentrasi memusatkan pesan "peace" di depan sebotol air, kristal air tadi mengembang bercabang-cabang dengan indahnya. Dan ketika dicoba dibacakan doa Islam, kristal bersegi enam dengan lima cabang daun muncul berkilauan. Subhanallah.
Dr. Emoto akhirnya berkeliling dunia melakukan percobaan dengan air di Swiss, Berlin, Prancis, Palestina, dan ia kemudian diundang ke Markas Besar PBB di New York untuk mempresentasikan temuannya pada bulan Maret 2005 lalu. Ternyata air bisa "mendengar" kata-kata, bisa "membaca" tulisan, dan bisa "mengerti" pesan. Dalam bukunya The Hidden Message in Water, Dr. Masaru Emoto menguraikan bahwa air bersifat bisa merekam pesan, seperti pita magnetik atau compact disk.
Semakin kuat konsentrasi pemberi pesan, semakin dalam pesan tercetak di air. Air bisa mentransfer pesan tadi melalui molekul air yang lain. Barangkali temuan ini bisa menjelaskan, kenapa air putih yang didoakan bisa menyembuhkan si sakit. Dulu ini kita anggap musyrik, atau paling sedikit kita anggap sekadar sugesti, tetapi ternyata molekul air itu menangkap pesan doa kesembuhan, menyimpannya, lalu vibrasinya merambat kepada molekul air lain yang ada di tubuh si sakit.
Tubuh manusia memang 75% terdiri atas air. Otak 74,5% air. Darah 82% air. Tulang yang keras pun mengandung 22% air. Air putih galon di rumah, bisa setiap hari didoakan dengan khusyu kepada Allah, agar anak yang meminumnya saleh, sehat, dan cerdas, dan agar suami yang meminum tetap setia. Air tadi akan berproses di tubuh meneruskan pesan kepada air di otak dan pembuluh darah. Dengan izin Allah, pesan tadi akan dilaksanakan tubuh tanpa kita sadari. Bila air minum di suatu kota didoakan dengan serius untuk kesalehan, insya Allah semua penduduk yang meminumnya akan menjadi baik dan tidak beringas.
Rasulullah saw. bersabda, "Zamzam lima syuriba lahu", "Air zamzam akan melaksanakan pesan dan niat yang meminumnya". Barangsiapa minum supaya kenyang, dia akan kenyang. Barangsiapa minum untuk menyembuhkan sakit, dia akan sembuh. Subhanallah ... Pantaslah air zamzam begitu berkhasiat karena dia menyimpan pesan doa jutaan manusia selama ribuan tahun sejak Nabi Ibrahim a.s.
Bila kita renungkan berpuluh ayat Al Quran tentang air, kita akan tersentak bahwa Allah rupanya selalu menarik perhatian kita kepada air.
Bahwa air tidak sekadar benda mati. Dia menyimpan kekuatan, daya rekam, daya penyembuh, dan sifat-sifat aneh lagi yang menunggu disingkap manusia. Islam adalah agama yang paling melekat dengan air. Shalat wajib perlu air wudlu 5 kali sehari. Habis bercampur, suami istri wajib mandi. Mati pun wajib dimandikan. Tidak ada agama lain yang menyuruh memandikan jenazah, malahan ada yang dibakar. Tetapi kita belum melakukan zikir air. Kita masih perlakukan air tanpa respek. Kita buang secara mubazir, bahkan kita cemari. Astaghfirullah.
Seorang ilmuwan Jepang telah merintis. Ilmuwan muslim harus melanjutkan kajian kehidupan ini berdasarkan Al Quran dan hadis.
Wallahu a'lam ...

Water is the chemical substance with chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
Water appears in nature in all three common states of matter and may take many different forms on Earth: water vapor and clouds in the sky; seawater and icebergs in the polar oceans; glaciers and rivers in the mountains; and the liquid in aquifers in the ground.
At high temperatures and pressures, such as in the interior of giant planets, it is argued that water exists as ionic water in which the molecules break down into a soup of hydrogen and oxygen ions, and at even higher pressures as superionic water in which the oxygen crystallises but the hydrogen ions float around freely within the oxygen lattice.[10]
The major chemical and physical properties of water are:
Water is a tasteless, odorless liquid at standard temperature and pressure. The color of water and ice is, intrinsically, a very slight blue hue, although water appears colorless in small quantities. Ice also appears colorless, and water vapor is essentially invisible as a gas.[11]
Water is transparent, and thus aquatic plants can live within the water because sunlight can reach them. Only strong UV light is slightly absorbed.
Since the water molecule is not linear and the oxygen atom has a higher electronegativity than hydrogen atoms, it carries a slight negative charge, whereas the hydrogen atoms are slightly positive. As a result, water is a polar molecule with an electrical dipole moment. Water also can form an unusually large number of intermolecular hydrogen bonds (four) for a molecule of its size. These factors lead to strong attractive forces between molecules of water, giving rise to water's high surface tension[12] and capillary forces. The capillary action refers to the tendency of water to move up a narrow tube against the force of gravity. This property is relied upon by all vascular plants, such as trees.
Water is a good solvent and is often referred to as the universal solvent. Substances that dissolve in water, e.g., salts, sugars, acids, alkalis, and some gases – especially oxygen, carbon dioxide (carbonation) are known as hydrophilic (water-loving) substances, while those that do not mix well with water (e.g., fats and oils), are known as hydrophobic (water-fearing) substances.
All the major components in cells (proteins, DNA and polysaccharides) are also dissolved in water.
Pure water has a low electrical conductivity, but this increases significantly with the dissolution of a small amount of ionic material such as sodium chloride.
The boiling point of water (and all other liquids) is dependent on the barometric pressure. For example, on the top of Mt. Everest water boils at 68 °C (154 °F), compared to 100 °C (212 °F) at sea level. Conversely, water deep in the ocean near geothermal vents can reach temperatures of hundreds of degrees and remain liquid.
Water has the second highest molar specific heat capacity of any known substance, after ammonia, as well as a high heat of vaporization (40.65 kJ·mol−1), both of which are a result of the extensive hydrogen bonding between its molecules. These two unusual properties allow water to moderate Earth's climate by buffering large fluctuations in temperature.
The maximum density of water occurs at 3.98 °C (39.16 °F).[13] It has the anomalous property of becoming less dense, not more, when it is cooled down to its solid form, ice. It expands to occupy 9% greater volume in this solid state, which accounts for the fact of ice floating on liquid water.

Water is miscible with many liquids, such as ethanol, in all proportions, forming a single homogeneous liquid. On the other hand, water and most oils are immiscible usually forming layers according to increasing density from the top. As a gas, water vapor is completely miscible with air.
Water forms an azeotrope with many other solvents.
Water can be split by electrolysis into hydrogen and oxygen.
As an oxide of hydrogen, water is formed when hydrogen or hydrogen-containing compounds burn or react with oxygen or oxygen-containing compounds. Water is not a fuel, it is an end-product of the combustion of hydrogen. The energy required to split water into hydrogen and oxygen by electrolysis or any other means is greater than the energy released when the hydrogen and oxygen recombine.[14]
Elements which are more electropositive than hydrogen such as lithium, sodium, calcium, potassium and caesium displace hydrogen from water, forming hydroxides. Being a flammable gas, the hydrogen given off is dangerous and the reaction of water with the more electropositive of these elements may be violently explosive.

This article is about general aspects of water. For a detailed discussion of its properties, see Properties of water. For other uses, see Water (disambiguation).
Water in three states: liquid, solid (ice), and (invisible) water vapor in the air. Clouds are accumulations of water droplets, condensed from vapor-saturated air.
Water is a chemical substance with the chemical formula H2O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state, water vapor or steam.
Water covers 70.9% of the Earth's surface,[1] and is vital for all known forms of life.[2] On Earth, it is found mostly in oceans and other large water bodies, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation.[3] Oceans hold 97% of surface water, glaciers and polar ice caps 2.4%, and other land surface water such as rivers, lakes and ponds 0.6%. A very small amount of the Earth's water is contained within biological bodies and manufactured products.
Water on Earth moves continually through a cycle of evaporation or transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land.
Clean drinking water is essential to human and other lifeforms. Access to safe drinking water has improved steadily and substantially over the last decades in almost every part of the world.[4][5] There is a clear correlation between access to safe water and GDP per capita.[6] However, some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability.[7] A recent report (November 2009) suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%.[8] Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70% of freshwater is consumed by agriculture.[9]
