حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ وَحَجَّاجٌ قَالَ حَدَّثَنِي شُعْبَةُ قَالَ سَمِعْتُ قَتَادَةَ يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَوُّوا صُفُوفَكُمْ فَإِنَّ تَسْوِيَةَ الصُّفُوفِ مِنْ تَمَامِ الصَّلَاةِ.

Muhammad ibn Ja'far told us: Shu'bah and Hajjaj told us — Hajjaj said: Shu'bah told me — I heard Qatadah narrating from Anas ibn Malik, that he said the Messenger of Allah, peace and blessings be upon him, said, "Straighten your rows, for straightening the rows is part of the completeness of prayer."
