Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: Sayyiduna Muawiyah (may Allah be pleased with him) performed prayer in Madinah Munawwarah. In it, he recited aloud, but he did not recite "Bismillah ir-Rahman ir-Rahim" aloud, neither before Surah al-Fatihah nor before the surah after al-Fatihah. Similarly, while bowing (i.e., going into ruku‘ or sujud), he did not say the takbir. When he completed the prayer and said salam, those Muhajirun and Ansar who heard his voice addressed him loudly, saying: O Sayyiduna Muawiyah! Did you make a deficiency in the prayer or did you forget? The narrator states: After that, in every prayer he performed, he recited "Bismillah ir-Rahman ir-Rahim" aloud, both before Surah al-Fatihah and before the surah after al-Fatihah, and he also said the takbir while going into sujud. All the narrators of this narration are trustworthy.
