Jami` at-Tirmidhi, Book 48, Hadith 233 (In-Book) ⓘ
Abu Hurairah narrated that the Messenger of Allah said: “Every Prophet has a (special) supplication which is answered. Verily, I have reserved mine as intercession for my nation, and it shall reach, if Allah wills, those of them who die, not associating anything with Allah.”
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لِكُلِّ نَبِيٍّ دَعْوَةٌ مُسْتَجَابَةٌ وَإِنِّي اخْتَبَأْتُ دَعْوَتِي شَفَاعَةً لأُمَّتِي وَهِيَ نَائِلَةٌ إِنْ شَاءَ اللَّهُ مَنْ مَاتَ مِنْهُمْ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
