Muwatta Malik, Book 15, Hadith 483 (In-Book) ⓘ
Yahya related to me from Malik that he had heard that it took Abdullah ibn Umar eight years to learn Surat al-Baqara. (Sura 2)
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، مَكَثَ عَلَى سُورَةِ الْبَقَرَةِ ثَمَانِيَ سِنِينَ يَتَعَلَّمُهَا .
