Once, he borrowed Úqūd al-Durriyyah fī Tanqīĥ al-Fatāwā al-Ĥamidiyyah of Ibn Áābidīn from the muĥaddith, Mawlānā Waşīy Aĥmad Sūratī. He read both volumes all through the night, until noon the next day and returned it. When Mawlānā Sūratī asked him in amazement: “Is one reading enough?” Alahazrat replied: “At least for the next two or three months, I will be able to cite the text [from anywhere in the book] in my fatāwā – and as far as the information therein is concerned, InShā’Allāh, I will remember it for the rest of my life.”
The book Al-Dawlatu’l Makkiyyah, penned in Makkah, was written largely out of memory.
 Shaykh al-Muĥaddithīn, Mawlānā Waşīy Aĥmad Sūratī [1252-1334/1836-1915] is the teacher of many úlamā; known for his marginalia on Máānī al-Aāthār of Imām Ţaĥāwī.
