When we prayed behind the Messenger of Allah ﷺ, one of us gave the salutation and pointed with his hand to the man to his right side and left side. When he finished his prayer, he said: What is the matter that one of you points with his hand (during prayer) just like the tails of restive horses. It is sufficient for one of you, or is it not sufficient for one of you to say in this manner? And he pointed with his finger; one should salute his brother at his right and left side. (Using translation from Abū Dāʾūd 998)   

كُنَّا إِذَا صَلَّيْنَا خَلْفَ رَسُولِ اللهِ ﷺ أَشَارَ أَحَدُنَا إِلَى أَخِيهِ مِنْ عَنْ يَمِينِهِ وَمِنْ عَنْ شِمَالِهِ فَلَمَّا صَلَّى رَسُولُ اللهِ ﷺ قَالَ مَا بَالُ أَحَدِكُمْ يَفْعَلُ هَذَا كَأَنَّهَا أَذْنَابُ خَيْلٍ شُمْسٍ إِنَّمَا يَكْفِي أَحَدَكُمْ أَنْ يَقُولَ هَكَذَا وَوَضَعَ يَمِينَهُ عَلَى فَخِذِهِ وَأَشَارَ بِأُصْبُعِهِ ثُمَّ يُسَلِّمُ عَلَى أَخِيهِ مِنْ عَنْ يَمِينِهِ وَمِنْ عَنْ شِمَالِهِ  

"I heard Jabir bin Samurah say: 'When we prayed behind the Prophet ﷺ we used to say: As-salamu 'alaykum, as-salamu 'alaykum (peace be upon you, peace be upon you)" - and Mis'ar (one of the narrators) pointed with his hand to the right and the left. He ﷺ said: 'What is the matter with these people who wave their hands as if they are the tails of wild horses? It is sufficient for one to place his hands on his thighs and to say the salam to his brother to his right and left." (Using translation from Nasāʾī 1318)  

سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ يَقُولُ كُنَّا إِذَا صَلَّيْنَا خَلْفَ النَّبِيِّ ﷺ قُلْنَا السَّلَامُ عَلَيْكُمِ السَّلَامُ عَلَيْكُمْ وَأَشَارَ مِسْعَرٌ بِيَدِهِ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ فَقَالَ «مَا بَالُ هَؤُلَاءِ يَرْفَعُونَ أَيْدِيَهُمْ كَأَنَّهَا أَذْنَابُ الْخَيْلِ الشُّمُسِ أَمَا يَكْفِي أَحَدَكُمْ أَوْ أَحَدَهُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمُ عَلَى أَخِيهِ مِنْ عَنْ يَمِينِهِ وَشِمَالِهِ»  

When we said prayer with the Messenger of Allah ﷺ, we pronounced: Peace be upon you and Mercy of Allah, peace be upon you and Mercy of Allah, and made gesture with the hand on both the sides. Upon this the Messenger of Allah (may peace be upon him said: What do you point out with your hands as if they are the tails of headstrong horses? This is enough for you that one should place one's hand on one's thigh and then pronounce salutation upon one's brother on the right side and then on the left. (Using translation from Muslim 431a)   

كُنَّا إِذَا صَلَّيْنَا خَلْفَ النَّبِيَّ ﷺ قُلْنَا السَّلَامُ عَلَيْكُمُ السَّلَامُ عَلَيْكُمْ وَأَشَارَ مِسْعَرٌ بِيَدِهِ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ فَقَالَ «مَا بَالُ هَؤُلَاءِ الَّذِينَ يُومِئُونَ بِأَيْدِيهِمْ كَأَنَّهَا أَذْنَابُ الْخَيْلِ الشُّمْسِ أَمَا يَكْفِي أَحَدُهُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمَ عَلَى أَخِيهِ عَنْ يَمِينِهِ وَشِمَالِهِ»  

[Machine] When we used to pray behind the Prophet ﷺ, we would say, by motioning with his index finger, "Assalamu alaikum, assalamu alaikum". Then the Prophet ﷺ said to us, "What is wrong with some people who throw their hands in prayer as if they were the tails of horses? Is it not sufficient for any of you, or for one of you, to place his hand on his thigh, then to greet his brother from his right and left (side)?"  

كُنَّا إِذَا صَلَّيْنَا خَلْفَ النَّبِيِّ ﷺ قُلْنَا يَعْنِي الْإِشَارَةَ بِإِصْبَعِهِ السَّبَابَةِ السَّلَامُ عَلَيْكُمْ السَّلَامُ عَلَيْكُمْ فَقَالَ لَنَا يَعْنِي النَّبِيَّ ﷺ مَا بَالُ أَقْوَامٍ يَرْمُونَ بِأَيْدِيهِمْ فِي الصَّلَاةِ كَأَنَّهَا أَذْنَابُ الْخَيْلِ الشُّمْسِ أَلَا يَكْفِي أَحَدَكُمْ أَوْ أَحَدَهُمْ أَنْ يَضَعَ يَدَهُ عَلَى فَخِذِهِ ثُمَّ يُسَلِّمَ عَلَى أَخِيهِ مِنْ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ  

[Machine] If we pray behind the Messenger of Allah ﷺ and one of us finishes his prayer, he should signal with his hand from his right and from his left. When he finishes, he should say, "What is the matter with any of you throwing his hand as if they are the tails of sunlit horses? Is it not sufficient for any of you to say like this?" And he pointed with his finger and greeted his brother from his right and from his left.  

إِذَا صَلَّيْنَا خَلْفَ رَسُولِ اللهِ ﷺ فَسَلَّمَ أَحَدُنَا أَشَارَ بِيَدِهِ مِنْ عَنْ يَمِينِهِ وَمِنْ عَنْ شِمَالِهِ فَلَمَّا صَلَّى قَالَ مَا بَالُ أَحَدِكُمْ يَرْمِي بِيَدِهِ كَأَنَّهَا أَذْنَابُ خَيْلٍ شُمْسٍ إِنَّمَا يَكْفِي أَوَلَا يَكْفِي أَحَدَكُمْ أَنْ يَقُولَ هَكَذَا وَأَشَارَ بِأُصْبُعِهِ وَيُسَلِّمُ عَلَى أَخِيهِ مِنْ عَنْ يَمِينِهِ وَمِنْ عَنْ شِمَالِهِ؟  

[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
