Muwatta Malik #178
Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَمِّهِ أَبِي سُهَيْلِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، أَنَّهُ قَالَ كُنَّا نَسْمَعُ قِرَاءَةَ عُمَرَ بْنِ الْخَطَّابِ عِنْدَ دَارِ أَبِي جَهْمٍ بِالْبَلاَطِ .
Yahya related to me from Malik from his paternal uncle Abu Suhayl
ibn Malik that his father said, "We heard the recitation of Umar ibn
al-Khattab when we were at the home of Abu Jahmin al-Balat." (Al-Balat
was a place in Madina between the mosque and the market.)
