Prayer
The Excellence of the Adhan and the Response to the Mu’adhdhin - Section 2
وَعَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: عَلَّمَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَن أَقُول عِنْد أَذَان الْمغرب: «اللَّهُمَّ إِن هَذَا إِقْبَالُ لَيْلِكَ وَإِدْبَارُ نَهَارِكَ وَأَصْوَاتُ دُعَاتِكَ فَاغْفِرْ لِي» . رَوَاهُ أَبُو دَاوُدَ وَالْبَيْهَقِيُّ فِي الدَّعَوَاتِ الْكَبِيرِ
Umm Salama said: God’s Messenger taught me to say when the adhan for the sunset prayer was called, “O God, this is the time when Your night comes on, Your day retires, and the voices of Your summoners are heard, so forgive me.” Abu Dawud transmitted it, as did Baihaqi in ad-Da'awat al-kabir.
