حَدَّثَنِي حَدَّثَنِي يَحْيَى ، عَنْ مَالِك ، عَنْ
نَافِعٍ ، أَنَّ
عُمَرَ بْنَ الْخَطَّابِ " كَانَ
يَأْمُرُ بِتَسْوِيَةِ الصُّفُوفِ ، فَإِذَا جَاءُوهُ فَأَخْبَرُوهُ ، أَنْ قَدِ اسْتَوَتْ كَبَّرَ "
It is narrated from Hazrat Nafi that Sayyiduna Umar bin Khattab (may Allah be pleased with him) used to order the people to straighten the rows, and when the people informed him that the rows had been straightened, he would then say the takbeer.
