عَنْ بُشَيْرِ بْنِ يَسَارٍ قَالَ: جَاءَ أَنَسُ بْنُ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ إِلَى الْمَدِينَةِ فَقُلْنَا لَهُ: مَا أَنْكَرْتَ مِنْ عَهْدِ نَبِيِّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ؟ فَقَالَ: مَا أَنْكَرْتُ مِنْكُمْ شَيْئًا غَيْرَ أَنَّكُمْ لَا تُقِيمُونَ صُفُوفَكُمْ
Bashir bin Yasar says: Sayyiduna Anas bin Malik (may Allah be pleased with him) came (to Madinah Munawwarah from Basrah). We asked him: What thing seems strange and new to you compared to the time of the Noble Prophet (peace and blessings be upon him)? He said: I do not find anything strange among you, except this one thing—that you do not straighten and align your rows.
