He (the prophet) taught me IQAMAH (to pronounce each phrase) twice: Allah is most great. Allah is most great. I testify that there is no god but Allah. I testify that there is no god but Allah; I testify that Muhammad is the Messenger of Allah, I testify that Muhammad is the Messenger of Allah: come to prayer, come to prayer: come to salvation, come to salvation: Allah is most great. Allah is great; there is no god but Allah. Abu Dawud said: The narrator ‘Abd al-Razzaq said; You pronounce IQAMAH for announcing the prayer; you must say twice: the time for prayer has come, the time for prayer has come. (The Prophet said to Abu Mahdhurah): did you listen (to me)? Abu Mahdhurah would not have the hair of his forehead cut, nor would he separate them (from him) because the Prophet ﷺ wiped over them. (Using translation from Abū Dāʾūd 501)   

عَنِ النَّبِيِّ ﷺ نَحْوَهُ وَفِيهِ الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ فِي الْأُولَى مِنَ الصُّبْحِ
