al-Haafith Ibn Hajar al-‘Asqalaanee said:
I drank some [Zam Zam water] once, whilst I was [just] beginning my studies in hadeeth, and asked Allaah to bless me with [strength of memory of] the calibre of ath-Thahabee in memorising hadeeth. I then performed hajj after a period of about 20 years, and found myself to have exceeded that level. So I asked Allaah for more than that, and I hope that Allaah will grant me that.
