It is narrated from Ubaid bin Rifaa that when Muawiyah (may Allah be pleased with him) came to Madinah, he led the prayer. He neither recited the “Bismillah ar-Rahman ar-Raheem” aloud nor said the takbeer when bowing and rising. When he finished the prayer with salam, the Muhajireen and Ansar called out to him: “O Muawiyah! You have stolen the prayer. Where is ‘Bismillah ar-Rahman ar-Raheem’? And when you bowed and rose, where was the takbeer?” Later, when he led another prayer, he said: This is the matter on which they criticized me.
