[Machine] He (the Prophet) came to the Prophet ﷺ and asked him to embrace Islam. So the Prophet ﷺ ordered him to perform ablution with water and sidr (a type of plant). He performed ablution and the prayer was established. He entered between Abu Bakr and Umar and stood between them. When he finished the prayer, the Prophet ﷺ said, "Qais ibn 'Asim asked me about three matters that no one else asked me about except Abu Bakr."  

أَنَّهُ قَدِمَ عَلَى النَّبِيِّ ﷺ فَاسْتَخْلَاهُ فَأَسْلَمَ «فَأَمَرَهُ النَّبِيُّ أَنْ يَغْتَسِلَ بِمَاءٍ وَسِدْرٍ» فَاغْتَسَلَ فَأُقِيمَتِ الصَّلَاةُ فَدَخَلَ بَيْنَ أَبِي بَكْرٍ وَعُمَرَ فَقَامَ بَيْنَهُمَا فَلَمَّا قَضَى الصَّلَاةَ قَالَ النَّبِيُّ ﷺ «لَقَدْ سَأَلَنِي قَيْسُ بْنُ عَاصِمٍ عَنْ ثَلَاثِ كَلِمَاتٍ مَا سَأَلَنِي عَنْهُنَّ غَيْرُ أَبِي بَكْرٍ»
