[Machine] I heard from the Messenger of Allah ﷺ that there is someone greater than me, and at that time I was a young boy. I used to memorize everything I heard from him. I prayed behind the Messenger of Allah ﷺ and I also prayed for Umm Ka'ab when she passed away while she was still a girl. The Messenger of Allah ﷺ stood up to pray for her in the midst of her funeral procession.
أَسْمَعُ مِنْ رَسُولِ اللهِ ﷺ أَنَّ هَاهُنَا مَنْ هُوَ أَكْبَرُ مِنِّي وَكُنْتُ لَيْلَتَئِذٍ غُلَامًا وَإِنِّي كُنْتُ لَأَحْفَظُ مَا أَسْمَعُ مِنْهُ صَلَّيْتُ وَرَاءَ رَسُولِ اللهِ ﷺ وَصَلَّى عَلَى أُمِّ كَعْبٍ مَاتَتْ وَهِيَ نُفَسَاءُ فَقَامَ رَسُولُ اللهِ ﷺ لِلصَّلَاةِ عَلَيْهَا وَسَطَهَا
