He used to inform them in every prayer of what he was reciting. Whatever the Messenger of Allah ﷺ recited aloud for us, we recite aloud for you, and whatever he kept silent from us, we keep silent from you.Ibn Bakr said, "In every prayer there is recitation."
حدثنا عبد الرزاق وابن بكر قالا أخبرنا ابن جريج أخبرني عطاء أنه
يخبرهم في كل صلاة يقرأ فما أسمعنا رسول الله ﷺ أسمعناكم وما أخفى علينا أخفينا عليكم قال ابن بكر في كل صلاة قرآن
Its isnad is sahih. Abu Awana related it in 1:125 from Dabari, from Abdul-Razzaq, with the same chain, but he did not give its wording, referring instead to what came before. The hadith is a repetition of 7494, and we noted some of its other routes there. Bukhari related it in 2:209, and Muslim in 1:116, both of them through the route of Ibn Ulaya, from Ibn Jurayj, with the same chain, but with an addition at the end.
