Abu Huraira narrated it from the Messenger of Allah (ﷺ) that they (the poor among the emigrants) said:
وَحَدَّثَنِي أُمَيَّةُ بْنُ بِسْطَامَ الْعَيْشِيُّ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا رَوْحٌ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُمْ قَالُوا يَا رَسُولَ اللَّهِ ذَهَبَ أَهْلُ الدُّثُورِ بِالدَّرَجَاتِ الْعُلَى وَالنَّعِيمِ الْمُقِيمِ . بِمِثْلِ حَدِيثِ قُتَيْبَةَ عَنِ اللَّيْثِ إِلاَّ أَنَّهُ أَدْرَجَ فِي حَدِيثِ أَبِي هُرَيْرَةَ قَوْلَ أَبِي صَالِحٍ ثُمَّ رَجَعَ فُقَرَاءُ الْمُهَاجِرِينَ . إِلَى آخِرِ الْحَدِيثِ وَزَادَ فِي الْحَدِيثِ يَقُولُ سُهَيْلٌ إِحْدَى عَشْرَةَ إِحْدَى عَشْرَةَ فَجَمِيعُ ذَلِكَ كُلِّهُ ثَلاَثَةٌ وَثَلاَثُونَ .
Messenger of Allah, the possessors of great wealth have obtained the highest ranks and lasting bliss, and the rest of the hadith is the same as transmitted by Qutaiba on the authority of Laith except that he inserted the words of Abu Salih in the narration of Abu Huraira that" the poor of the emigrants came back," to the end of the hadith,, but this addition was made that Suhail said (that every part of the supplication, i. e. Glorification of Allah, His Praise and declaration of His Greatness) should be uttered eleven times making the total as thirty-three.
