وَعَنْ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا قَالَ الْمُؤَذِّنُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ فَقَالَ أَحَدُكُمُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ثُمَّ قَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ قَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ ثُمَّ قَالَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ قَالَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ثُمَّ قَالَ حَيَّ عَلَى الصَّلَاةِ قَالَ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ ثُمَّ قَالَ حَيَّ عَلَى الْفَلَاحِ قَالَ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ ثُمَّ قَالَ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ قَالَ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ثُمَّ قَالَ لَا إِلَهَ إِلَّا اللَّهُ قَالَ لَا إِلَهَ إِلَّا اللَّهُ مِنْ قَلْبِهِ دخل الْجنَّة» . رَوَاهُ مُسلم

When the mu’adhdhin says, “God is most great, God is most great,” and one of you makes the response, “God is most great, God is most great”; then says, “I testify that there is no god but God,” and he makes the response, “I testify that there is no god but God”; then says, “I testify that Muhammad is God’s Messenger,” and he makes the response, “I testify that Muhammad is God’s Messenger”; then says, “Come to prayer,” and he makes the response, “There is no might and no power except in God”; then says, “Come to salvation,” and he makes the response, “There is no might and no power except in God”; then says, “God is most great, God is most great,” and he makes the response, “God is most great, God is most great”; then says, “There is no god but God,” and he makes the response, “There is no god but God”; if he says this from his heart, he will enter paradise.
