Muwatta Malik, Book 3, Hadith 184 (In-Book) ⓘ

Yahya related to me from Malik from Yahya ibn Said and Rabia ibn Abi Abd arRahman from al-Qasim ibn Muhammad that al Furafisa ibn Umayral-Hanafi said, "I only learnt Sura Yusuf (Sura 12) from the recitation of it by Uthman ibn Affan in the subh prayer because of the great number of times he repeated it to us."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، وَرَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، أَنَّ الْفُرَافِصَةَ بْنَ عُمَيْرٍ الْحَنَفِيَّ، قَالَ مَا أَخَذْتُ سُورَةَ يُوسُفَ إِلاَّ مِنْ قِرَاءَةِ عُثْمَانَ بْنِ عَفَّانَ إِيَّاهَا فِي الصُّبْحِ مِنْ كَثْرَةِ مَا كَانَ يُرَدِّدُهَا لَنَا ‏.‏
