Lady Aisha (may Allah be pleased with her) narrates: The Noble Prophet (peace and blessings be upon him) forbade performing ablution with water that has been left in the sun, or bathing with it. The Noble Prophet (peace and blessings be upon him) said: "As a result of this, leukoderma (vitiligo) may occur." The narrator of this narration, Umar bin Muhammad Asam, is considered unreliable in hadith. No one else besides him has narrated this from Faleeh, and regarding its attribution to Zuhri, this hadith is not authentic.
