Hadith 501790
Chapter 3: Prayer - كتاب الصلاة
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.)
