Abdullah saw a man who was praying with his feet together. He said: "He is going against the Sunnah; if he shifted his weight from one to the other that would be better." (Using translation from Nasāʾī 892)
أَنَّ عَبْدَ اللهِ رَأَى رَجُلًا يُصَلِّي قَدْ صَفَّ بَيْنَ قَدَمَيْهِ فَقَالَ «خَالَفْتَ السَّنَةَ لَوْ رَاوَحْتَ بَيْنَهُمَا كَانَ أَفْضَلُ»
