O Abu Huraira, what is this takbir? He said: Verily it is the prayer of the Messenger of Allah ﷺ.  

مسلم:٣٩٢e – حَدَّثَنَا مُحَمَّدُ بْنُ مِهْرَانَ الرَّازِيُّ حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ حَدَّثَنَا الأَوْزَاعِيُّ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ عَنْ أَبِي سَلَمَةَ

أَنَّ أَبَا هُرَيْرَةَ كَانَ يُكَبِّرُ فِي الصَّلاَةِ كُلَّمَا رَفَعَ وَوَضَعَ فَقُلْنَا يَا أَبَا هُرَيْرَةَ مَا هَذَا التَّكْبِيرُ قَالَ إِنَّهَا لَصَلاَةُ رَسُولِ اللَّهِ ﷺ
