حَدَّثَنَا مُحَمَّدُ بْنُ مِهْرَانَ ، حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ ، عَنِ الأَوْزَاعِيِّ ، أَخْبَرَنِي إِسْحَاقُ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ ، يَذْكُرُ ذَلِكَ .
It is reported on the authority of Abu Talha that he had heard Anas b. Malik narrating this.
