Musnad Ahmad Hadith 11140

Saeed bin Harith (may Allah be pleased with him) narrates that once Abu Hurairah (may Allah be pleased with him) became ill, so Abu Saeed Khudri (may Allah be pleased with him) led us in prayer. At the beginning of the prayer, when going into ruku, he said the takbeer aloud, also when saying "Sami Allahu liman hamidah," when raising his head from prostration and going into prostration, and when standing up between the two rak'ahs, he said the takbeer aloud, and in this way he completed his prayer. After the prayer, someone said to him that people have differed regarding your prayer. Upon this, he stood near the pulpit and said, "By Allah, I do not care whether your prayers are different from this or not. I have seen the Prophet (ﷺ) praying in this manner."
