The Book of Tribulations and Portents of the Last Hour
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بُعِثْتُ أَنَا وَالسَّاعَةُ كَهَاتَيْنِ " . قَالَ شُعْبَةُ وَسَمِعْتُ قَتَادَةَ يَقُولُ فِي قَصَصِهِ كَفَضْلِ إِحْدَاهُمَا عَلَى الأُخْرَى فَلاَ أَدْرِي أَذَكَرَهُ عَنْ أَنَسٍ أَوْ قَالَهُ قَتَادَةُ .Anas b. Malik reported that Allah's Messenger (way peace be upon him) said:I and the Last Hour have been sent like this. Shu'ba said: I heard Qatada as saying in his narration: The excellence of one over the other. And I do not know whether he narrated it from Anas or Qatada himself said so
From Sahih Muslim, whose reports the scholars accept as authentic.
