Water in a dream signifies Islam, knowledge, life, fertility, and prosperity, because all living things depend on it for life. If one sees himself drinking plenty of clear, fresh water, it indicates a long life and a pure livelihood. If he drinks it from a well easily, he will gain wealth through the cunning of a wicked man. Stagnant water indicates confinement and prison. Murky water signifies a miserable life, and salty water indicates distress and worry. Hot water represents torment and illness. Whoever sees himself giving water in a cup to another, it indicates a child. Water flowing in houses or markets indicates strife and calamities. Walking on water indicates strong faith and certainty.

Water indicates a good life, sustenance, and livelihood, and it can indicate marriage. Drinking clear, fresh water signifies recovery from illnesses and lawful sustenance. If the dreamer is a disbeliever, he will convert to Islam. Whoever sees himself in murky water or mud is in worry, grief, and illness. Whoever bathes with cold water indicates repentance, healing, release from prison, and payment of debt. Bathing with hot water in winter indicates benefit and profit, but in summer, it indicates worry and illness. Whoever sees water coming out of a wall, it signifies that worry will afflict him from a man or an in-law.

The vision of water is interpreted in several ways: it represents a good life, sustenance, livelihood, strength, and marriage. Clear water is better than murky, and flowing water is better than stagnant. Whoever sees himself drinking from a river's water will acquire wealth from a man of great stature, proportional to the amount he drank. Bitter water indicates a miserable life, and yellow water indicates illness. Whoever sees himself fall into water without reaching the bottom will get involved in worldly affairs and attain a blessing. If he reaches the bottom, severe grief will afflict him.
