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 ‏"‏ ‏.‏

It wasnarrated from Anas bin Malik that the Messenger of Allah (ﷺ) said

Qatadah (the Tabi'ee in the chain) would narrate after this hadith that Anas (ra) said "Those who said 'La illaha illa Allah' (there is no god except Allah) and had the weight of a grain of barley in good in his heart will come out of the Fire, and those who said 'La illaha illa Allah' and had a weight of a grain of wheat in good in his heart will come out of the Fire, and those who said 'La illaha illa Allah' and had a weight of a grain of dust in good in his heart will come out of the Fire."
