النسائي:٨٩٢ – أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ قَالَ حَدَّثَنَا يَحْيَى عَنْ سُفْيَانَ بْنِ سَعِيدٍ الثَّوْرِيِّ عَنْ مَيْسَرَةَ عَنِ الْمِنْهَالِ بْنِ عَمْرٍو عَنْ أَبِي عُبَيْدَةَ

أَنَّ عَبْدَ اللَّهِ رَأَى رَجُلاً يُصَلِّي قَدْ صَفَّ بَيْنَ قَدَمَيْهِ فَقَالَ خَالَفَ السُّنَّةَ وَلَوْ رَاوَحَ بَيْنَهُمَا كَانَ أَفْضَلَ
