Is it not sufficient for one of you or for one of them that he puts his hand on his thigh, and then gives the salutation to his brother to his right and left sides.  

أَمَا يَكْفِي أَحَدَكُمْ أَوْ أَحَدَهُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمُ عَلَى أَخِيهِ مَنْ عَنْ يَمِينِهِ وَمَنْ عَنْ شِمَالِهِ  

[Machine] When we used to pray behind the Prophet ﷺ , we would say, "Peace be upon you with our right hand and our left hand." The Messenger of Allah ﷺ said, "Why do I see your hands resembling the tails of horses? It is enough for one of you to place his hand on his thigh and then greet with his right hand and his left hand."  

كُنَّا إِذَا صَلَّيْنَا خَلْفَ النَّبِيِّ ﷺ قُلْنَا بِأَيْدِينَا السَّلَامُ عَلَيْكُمْ يَمِينًا وَشِمَالًا فَقَالَ رَسُولُ اللَّهِ ﷺ «مَا لِي أَرَى أَيْدِيَكُمْ كَأَنَّهَا أَذْنَابُ خَيْلٍ شُمْسٍ إِنَّمَا يَكْفِي أَحَدَكُمْ أَنْ يَضَعَ يَدَيْهِ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمُ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ»  

[Machine] "When we used to be with the Messenger of Allah ﷺ , one of us would raise his right and left hand. The Messenger of Allah ﷺ then said, 'Why do I see you raising your hands as if they are the tails of horses being whipped by the sun? Isn't it enough for one of you to place his hand on his thigh and then greet the one on his right and the one on his left?'"  

كُنَّا إِذَا كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ رَفَعَ أَحَدُنَا يَدَهُ يُمْنَةً وَيُسْرَةً فَقَالَ رَسُولُ اللَّهِ ﷺ «مَا لِي أَرَاكُمْ رَافِعِي أَيْدِيكُمْ كَأَنَّهَا أَذْنَابُ خَيْلٍ شُمْسٍ أَوَلَا يَكْفِي أَحَدَكُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمُ عَلَى مَنْ عَنْ يَمِينِهِ وَمَنْ عَنْ يَسَارِهِ»  

[Machine] I heard Jabir ibn Samurah saying, "We used to pray with the Prophet ﷺ and when we greeted him with salaam, we would say 'As-salamu 'alaykum, as-salamu 'alaykum.' He said, 'What is the matter with some people that they wave their hands as if they were tails of horses in the sun? Does it not suffice for one of you to place his hand on his thigh and then greet his brother on his right and left?'"  

سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ يَقُولُ كُنَّا نُصَلِّي مَعَ النَّبِيِّ ﷺ فَنَقُولُ بِأَيْدِينَا السَّلَامُ عَلَيْكُمُ السَّلَامُ عَلَيْكُمْ فَقَالَ «مَا بَالُ أَقْوَامٍ يُلْقُونَ أَيْدِيَهُمْ كَأَنَّهَا أَذْنَابُ خَيْلٍ شُمُسٍ أَلَا يَكْفِي أَحَدَكُمْ أَوْ إِنَّمَا يَكْفِي أَحَدَكُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمُ عَلَى أَخِيهِ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ»  

"We used to pray behind the Messenger of Allah ﷺ and we would greet (others) with our hands. He said: 'What is the matter with those who greet (others) with their hands as if they were tails of wild horses? It is sufficient for any one of you to put his hand on his thigh and say: "As-salamu 'alaikum, as-salamu 'alaikum." (Using translation from Nasāʾī 1185)  

كُنَّا نُصَلِّي خَلْفَ النَّبِيَّ ﷺ فَنُسَلِّمُ بِأَيْدِينَا فَقَالَ مَا بَالُ هَؤُلَاءِ يُسَلِّمُونَ بِأَيْدِيهِمْ كَأَنَّهَا أَذْنَابُ خَيْلِ شَمْسٍ إِنَّمَا يَكْفِي أَحَدَكُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يَقُولُ السَّلَامُ عَلَيْكُمُ السَّلَامُ عَلَيْكُمْ  

"مَا بَالُ الَّذِينَ يَرْنونَ (*) بِأَيدِيهم فِي الصَّلاةِ كَأَنَّهَا أَذْنَابُ الْخَيلِ الشُّمْسِ، ألا يَكْفِي أَحَدُكُمْ أن يَضَعَ يَدَهُ عَلَى فَخذِه، ثُمَّ يُسَلِّم عَلَى أَخِيهِ عَن يَمِينِهِ وَشِمَالِهِ".  

"مَا بَالُ هَؤُلاءِ يُسَلِّمُونَ بأَيديهِم كَأَنَّهَا (*) أذْنَابُ خَيلٍ شُمْسٍ، أَمَا يَكْفِي أَحَدَهُمْ أَنْ يَضَع يَدَهُ عَلَى فَخذِه، يَقُولُ: السَّلامُ عَلَيكُمْ، السَّلامُ عَليكُمْ" .  

"عَلامَ تُؤمِنُونَ بأَيديكم؟ كَأنَّهَا أَذنَابُ خَيلٍ شُمْسٍ، وَإِنَّمَا يَكْفى أَحَدَكم أَن يَضَعَ يَدَهُ عَلَى فَخِذهِ ثُمَّ يُسَلِّمُ عَلَى أَخِيهِ. مَن عَلَى يمِينِهِ وَشِمالِهِ".
