Muwatta Malik, Book 16, Hadith 23 (USC-MSA) ⓘ
Yahya related to me from Malik from Nafi that Abdullah ibn Umar said, "The prayer over Umar ibn al-Khattab was done in the mosque."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ صُلِّيَ عَلَى عُمَرَ بْنِ الْخَطَّابِ فِي الْمَسْجِدِ .
