"When the Messenger of Allah departed he reined in his she-camel until its head touched the middle of his saddle, and he was saying to the people: 'Be tranquil be tranquil,' on the evening of Arafat." (Using translation from Nasāʾī 3019)  

أَنَّهُ سَمِعَ ابْنَ عَبَّاسٍ يَقُولُ لَمَّا دَفَعَ رَسُولُ اللهِ ﷺ شَنَقَ نَاقَتَهُ حَتَّى إِنَّ رَأْسَهَا لَيَمَسُّ وَاسِطَةَ رَحْلِهِ وَهُوَ يَقُولُ لِلنَّاسِ «السَّكِينَةُ السَّكِينَةُ عَشِيَّةَ عَرَفَةَ»  

[Machine] The Messenger of Allah, ﷺ , left Arafat and upon him was tranquility, and he commanded us to be tranquil. Then he said, "Take your rituals from me, for I may not meet you after this year, and throw pebbles like the size of the pebbles used in stoning."  

أَفَاضَ رَسُولُ اللهِ ﷺ مِنْ عَرَفَةَ وَعَلَيْهِ السَّكِينَةُ وَأَمَرَنَا بِالسَّكِينَةِ ثُمَّ قَالَ «خُذُوا مَنَاسِكَكُمْ لِعَلِّي لَا أَلْقَاكُمْ بَعْدَ عَامِي هَذَا وَارْمُوا بِمِثْلِ حَصَى الْخَذْفِ»  

"Be tranquil, O slaves of Allah!" gesturing with his hand like this - and Ayyub gested with his palm uppermost. (Using translation from Nasāʾī 3022)  

أَنَّ النَّبِيَّ ﷺ لَمَّا أَفَاضَ مِنْ عَرَفَةَ جَعَلَ يَقُولُ «السَّكِينَةَ عِبَادَ اللهِ» يَقُولُ بِيَدِهِ هَكَذَا وَأَشَارَ أَبُو أَيُّوبَ بِبَاطِنِ كَفِّهِ إِلَى السَّمَاءِ
