[Machine] When we used to pray behind the Prophet ﷺ , we would say as a sign with his index finger: "Peace be upon you, peace be upon you." The Prophet ﷺ then said to us, "Why do some people throw their hands during prayer as if they were the tails of wild horses at sunset? Is it not enough for one of you to place his hand on his thigh and then say the salaam by turning his hand to the right and left?"
كُنَّا إِذَا صَلَّيْنَا خَلْفَ النَّبِيِّ ﷺ قُلْنَا يَعْنِي الْإِشَارَةَ بِأُصْبُعِهِ السَّبَابَةِ السَّلَامُ عَلَيْكُمْ السَّلَامُ عَلَيْكُمْ فَقَالَ لَنَا يَعْنِي النَّبِيَّ ﷺ مَا بَالُ أَقْوَامٍ يَرْمُونَ بِأَيْدِيهِمْ فِي الصَّلَاةِ كَأَنَّهَا أَذْنَابُ الْخَيْلِ الشُّمْسِ أَمَا يَكْفِي أَحَدَهُمْ أَوْ أَحَدَكُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمَ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ
