"Abu Qilabah said to me (Ayyub): He ('Amr) is still alive, do you want to meet him?" I met him and asked him, and he said: "When Makkah was conquered, all the people hastened to announce their Islam. My father went to announce the Islam of the poeple of our village, and when he came back we went to see him and he said: 'By Allah, I have indeed come to you from the Messenger of Allah ﷺ'. He said: 'Pray such and such a prayer at such and such a time, pray such and such a prayer at such and such a time. When the time for prayer comes let one of you call the Adhan and let the one who knows the most Qur'an lead the prayer.'"  

لِي أَبُو قِلاَبَةَ هُوَ حَىٌّ أَفَلاَ تَلْقَاهُ قَالَ أَيُّوبُ فَلَقِيتُهُ فَسَأَلْتُهُ فَقَالَ لَمَّا كَانَ وَقْعَةُ الْفَتْحِ بَادَرَ كُلُّ قَوْمٍ بِإِسْلاَمِهِمْ فَذَهَبَ أَبِي بِإِسْلاَمِ أَهْلِ حِوَائِنَا فَلَمَّا قَدِمَ اسْتَقْبَلْنَاهُ فَقَالَ جِئْتُكُمْ وَاللَّهِ مِنْ عِنْدِ رَسُولِ اللَّهِ ﷺ حَقًّا فَقَالَ صَلُّوا صَلاَةَ كَذَا فِي حِينِ كَذَا وَصَلاَةَ كَذَا فِي حِينِ كَذَا فَإِذَا حَضَرَتِ الصَّلاَةُ فَلْيُؤَذِّنْ لَكُمْ أَحَدُكُمْ وَلْيَؤُمَّكُمْ أَكْثَرُكُمْ قُرْآنًا
