Is it permissible to make du'a (supplication) when drinking Zamzam water for any worldly or otherworldly purpose?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: When I drink from the water of Zamzam, I supplicate to Allah (Exalted and Majestic is He) to fill my heart with faith and wisdom. What is the ruling on this action?

Answer:
You may supplicate to Allah for whatever you wish. Zamzam water is for whatever it is drunk for. If you drink it for the sake of blessing, or for treatment and healing, or for any other purpose, it is blessed. Zamzam water is for whatever it is drunk for. If you drink it for the sake of knowledge and jurisprudence, or otherwise, it depends on the intention. Drinking is an act of worship; drinking Zamzam water is an act of worship. It contains worship. Yes, it is not merely a matter of quenching thirst, but it is an act of worship that carries reward. Yes.
