وَعَنْ عَمْرِو بْنِ سَلَمَةَ
قَالَ: قَالَ أَبِي: «جِئْتُكُمْ مِنْ عِنْدِ اَلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَقًّا. قَالَ: «فَإِذَا حَضَرَتْ اَلصَّلَاةُ فَلْيُؤَذِّنْ أَحَدُكُمْ، وَلْيَؤُمَّكُمْ أَكْثَرُكُمْ قُرْآنًا«, قَالَ: فَنَظَرُوا فَلَمْ يَكُنْ أَحَدٌ أَكْثَرَ قُرْآنًا مِنِّي، فَقَدَّمُونِي، وَأَنَا اِبْنُ سِتٍّ أَوْ سَبْعِ سِنِينَ»
My father said, “I have come from the true Prophet (sallallahu alayhi wa sallam), so when the time of Salat (prayer) comes one of you should announce the Adhan and the one of you who knows the Qur’an most should be your Imam.” He (Amr) said: “They looked around and there was no one who knew the Qur’an more than I. So they put me forward in front of them and I was only six or seven years old.”.
