Majma’ bin Yahya narrates: I was sitting with Abu Umamah bin Sahl. The muezzin came and said «اللہ اکبر» «اللہ اکبر», so Sayyiduna Abu Umamah (may Allah be pleased with him) said the same. The muezzin said «اشهد ان لا اله الا الله», so Sayyiduna Abu Umamah (may Allah be pleased with him) said the same. The muezzin said «اشهد ان محمدا رسول اللہ», so Sayyiduna Abu Umamah (may Allah be pleased with him) said the same. Then he turned to me and said: Sayyiduna Muawiyah (may Allah be pleased with him) narrated to me a hadith from the Prophet (peace and blessings be upon him) in this manner.
