Is it permissible for a person to write the Name of Allah, erase it with water, and then drink the water
when asking Allah (Glorified be He) for a certain need?
We do not know of any Shari`ah-based evidence that proves the permissibility of this practice. A person is permitted to supplicate to Allah (Glorified and Exalted be He) with Islamically acceptable Du`a' (supplications). It is better to refer to the following books for Du`a'; Al-Adhkar by
Al-Nawawy, Al-Wabil Al-Sayyib by
Ibn Al-Qayyim, `Amal Al-Yawm wal-Laylah by
Al-Nasa'y, and Jami` Al-Usul.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
