Muwatta Malik, Book 9, Hadith 422 (In-Book) ⓘ
Yahya related to me from Malik from Ibn Shihab from Said ihn al-Musayyab that Umar ibn al Khattab and Uthman ibn Affan, may Allah be pleased with them, used to do the same.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، وَعُثْمَانَ بْنَ عَفَّانَ، - رضى الله عنهما - كَانَا يَفْعَلاَنِ ذَلِكَ .
