One day, two men who were students and close companions of Sheikh Abdullah Sirāj al-Dīn1 were quarrelling with one another. One of them said to the other, “If the Sheikh has not memorised more than 100,000 Hadiths, then my wife is divorced!”2. Then they both went to the Sha’bāniyya Madrassa to ask the Sheikh directly and to seek his fatwa about what occurred between them. The Sheikh lowered his head and then said to the man (who uttered the potential words of divorce):
“You have not divorced your wife. But I strongly advise you to distance your tongue from uttering words of divorce and haram speech!” 3 4
1] Sheikh Abdullah Sirāj al-Dīn was one of the greatest scholars and Friends of Allah (awliya) of recent times. His books (in Arabic) are available for free download here and some of his books have been translated into English and are available here. You can listen to a rare recording of him reciting the Quran here.
2] It seems they were arguing about how many Hadiths the Sheikh had memorised. One of the men was so sure that the number was above 100,000 that he made such a risky statement.
3] This means that the Sheikh had memorised the text of the Hadiths and also the chains of transmission (asāneed).
