Hazrat Muhammad bin Amr narrates that my respected father narrated from my grandfather that I was with Sayyiduna Muawiyah bin Abi Sufyan (may Allah be pleased with them) when the muezzin said « اللهُأَكْبَرُ،اللهُأَكْبَرُ » "Allah is the Greatest, Allah is the Greatest," so Sayyiduna Muawiyah (may Allah be pleased with him) said « اللهُأَكْبَرُ،للهُأَكْبَرُ », then he (the muezzin) said « أَشْهَدُأَنْلَاإِلَهَإِلَّااللهُ » "I bear witness that there is no deity worthy of worship except Allah," so Sayyiduna Muawiyah (may Allah be pleased with him) also said « أَشْهَدُأَنْلَاإِلَهَإِلَّااللهُ », then he (the muezzin) said « أَشْهَدُأَنْمُحَمَّدٌرَسُولُٱللَّٰه » "I bear witness that Muhammad (peace and blessings of Allah be upon him) is the Messenger of Allah." So Sayyiduna Muawiyah (may Allah be pleased with him) also said « أَشْهَدُأَنْمُحَمَّدٌرَسُولُٱللَّٰه », then he (the muezzin) said « حَيَّعَلَىالصَّلَاةِ » "Come to prayer," so Sayyiduna Muawiyah (may Allah be pleased with him) said « لَاحَوْلَوَلَاقُوَّةَإِلَّابِاللَٰهِ » "There is no power to do good and no strength to avoid evil except with Allah's help." Then he (the muezzin) called « حَيَّعَلَىالْفَلَاحِ » "Come to success," so Sayyiduna Muawiyah (may Allah be pleased with him) said « لَاحَوْلَوَلَاقُوَّةَإِلَّابِاللَٰهِ », then he (the muezzin) said « اللهُأَكْبَرُ ، اللهُأَكْبَرُ ، لَاإِلَهَإِلَّااللهُ » "Allah is the Greatest, Allah is the Greatest, there is no deity except Allah." So Sayyiduna Muawiyah (may Allah be pleased with him) also said « اللهُأَكْبَرُ،اللهُأَكْبَرُ،لَاإِلَهَإِلَّااللهُ ». Then he said that the Messenger of Allah (peace and blessings of Allah be upon him) used to say likewise. Imam Abu Bakr (may Allah have mercy on him) says that the hadith of Sayyiduna Umar bin Khattab (may Allah be pleased with him) is also related to this chapter; I have mentioned it in another chapter. Imam Abu Bakr (may Allah have mercy on him) says that the meaning of the hadith of Sayyidah Umm Habibah (may Allah be pleased with her) is that the Messenger of Allah (peace and blessings of Allah be upon him), while responding to the adhan, said the same words as the muezzin until he finished the adhan, except for « حَيَّعَلَىالصَّلَاةِ » and « حَيَّعَلَىالْفَلَاحِ », (in response to these he said « لَاحَوْلَوَلَاقُوَّةَإِلَّابِاللَٰهِ »). Likewise, the meaning of the hadith of Sayyiduna Abu Saeed Khudri (may Allah be pleased with him) is also that you should respond to the adhan in the same way as the muezzin says, except for « حَيَّعَلَىالصَّلَاةِ » and « حَيَّعَلَىالْفَلَاحِ ». The ahadith of Sayyiduna Umar bin Khattab and Sayyiduna Muawiyah (may Allah be pleased with them) explain these two ahadith. In the ahadith of Sayyiduna Umar and Sayyiduna Muawiyah (may Allah be pleased with them), it is stated that whoever hears the adhan for prayer from the muezzin should repeat the words just as the muezzin says, except for the words « حَيَّعَلَىالصَّلَاةِ » and « حَيَّعَلَىالْفَلَاحِ », in response to these words he should say « لَاحَوْلَوَلَاقُوَّةَإِلَّابِاللَٰهِ ».
