The freed slave of Sayyiduna Uthman bin Affan, Hazrat Muhammad bin Yusuf (may Allah have mercy on him), narrates that when the muezzin gave the adhan and said: « اللهُأَكْبَرُ،للهُأَكْبَرُ » "Allah is the Greatest, Allah is the Greatest," then Sayyiduna Muawiyah bin Abi Sufyan (may Allah be pleased with him) said « اللهُأَكْبَرُ،للهُأَكْبَرُ » so he said « أَشْهَدُأَنْلَاإِلَهَإِلَّااللهُ » "I bear witness that there is no deity worthy of worship except Allah," Sayyiduna Muawiyah (may Allah be pleased with him) also said « أَشْهَدُأَنْلَاإِلَهَإِلَّااللهُ » he said « أَشْهَدُأَنْمُحَمَّدٌرَسُولُٱللَّٰه » "I bear witness that Muhammad (peace and blessings be upon him) is the Messenger of Allah." Sayyiduna Muawiyah (may Allah be pleased with him) also said « أَشْهَدُأَنْمُحَمَّدٌرَسُولُٱللَّٰه » Then Sayyiduna Muawiyah (may Allah be pleased with him) said that I heard the Messenger of Allah (peace and blessings be upon him) saying in this manner.
