Ibn ‘Abbaas (may Allaah be pleased with him) drank from the water of Zamzam and made du’a: “O Allaah, I ask you for beneficial knowledge, plentiful provision and healing from every disease (اللَّهُمَّ إِنِّي أَسْأَلُكَ عِلْمَاً نَافِعَاًً وَرِزْقَاً وَاسِعَاًَ وَشِفَاءً مِنْ كُلِّ دَاءٍ).”
(Al Hakim)
