It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: “Every Prophet had a prayer that was answered, and every Prophet offered this prayer in this world. But I am saving my prayer so that I can intercede for my nation, and it reaches every one of them who dies not associating anything with Allah.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لِكُلِّ نَبِيٍّ دَعْوَةٌ مُسْتَجَابَةٌ فَتَعَجَّلَ كُلُّ نَبِيٍّ دَعْوَتَهُ وَإِنِّي اخْتَبَأْتُ دَعْوَتِي شَفَاعَةً لأُمَّتِي فَهِيَ نَائِلَةٌ مَنْ مَاتَ مِنْهُمْ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا " .
