Abu Salama narrated that Abu Huraira told him that when the Messenger of Allah (ﷺ) pronounced:
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا حُسَيْنُ بْنُ مُحَمَّدٍ ، حَدَّثَنَا شَيْبَانُ ، عَنْ يَحْيَى ، عَنْ أَبِي سَلَمَةَ ، أَنَّ أَبَا هُرَيْرَةَ ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم بَيْنَمَا هُوَ يُصَلِّي الْعِشَاءَ إِذْ قَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . ثُمَّ قَالَ قَبْلَ أَنْ يَسْجُدَ " اللَّهُمَّ نَجِّ عَيَّاشَ بْنَ أَبِي رَبِيعَةَ " . ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ الأَوْزَاعِيِّ إِلَى قَوْلِهِ " كَسِنِي يُوسُفَ " . وَلَمْ يَذْكُرْ مَا بَعْدَهُ .
" Allah listened to him who praised Him." and before prostration, he would recite this in the 'Isya' prayer: O Allah! rescue 'Ayyash b. Abu Rabi'a, and the rest of the hadith is the same as narrated by Auza'i to the words:" Like the famine (at the time) if Joseph." but he made no mention of that which follows afterwards.
