[Machine] He heard Abu Huraira saying that the Messenger of Allah ﷺ used to say "Allahu Akbar" (Allah is the Greatest) when he stood up to pray, and he mentioned something similar to that.  

أحمد:٧٦٥٩ – حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا ابْنُ جُرَيْجٍ أَخْبَرَنِي ابْنُ شِهَابٍ عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ كَانَ رَسُولُ اللهِ ﷺ إِذَا قَامَ إِلَى الصَّلَاةِ يُكَبِّرُ فَذَكَرَ نَحْوَهُ
