And Abu Huraira said, "When Allah's Messenger (ﷺ) raised his head from (bowing) he used to say "Sami`a l-lahu liman hamidah, Rabbana wa laka l-hamd." He Would invoke Allah for some people by naming them:"O Allah! Save Al-Walid bin Al-Walid and Salama bin Hisham and `Aiyash bin Abi Rabi`a and the weak and the helpless people among the faithful believers O Allah! Be hard on the tribe of Mudar and let them suffer from famine years like that of the time of Joseph." In those days the Eastern section of the tribe of Mudar was against the Prophet.
قَالاَ وَقَالَ أَبُو هُرَيْرَةَ ـ رضى الله عنه ـ وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم حِينَ يَرْفَعُ رَأْسَهُ يَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ، رَبَّنَا وَلَكَ الْحَمْدُ. يَدْعُو لِرِجَالٍ فَيُسَمِّيهِمْ بِأَسْمَائِهِمْ فَيَقُولُ " اللَّهُمَّ أَنْجِ الْوَلِيدَ بْنَ الْوَلِيدِ وَسَلَمَةَ بْنَ هِشَامٍ وَعَيَّاشَ بْنَ أَبِي رَبِيعَةَ، وَالْمُسْتَضْعَفِينَ مِنَ الْمُؤْمِنِينَ، اللَّهُمَّ اشْدُدْ وَطْأَتَكَ عَلَى مُضَرَ، وَاجْعَلْهَا عَلَيْهِمْ سِنِينَ كَسِنِي يُوسُفَ ". وَأَهْلُ الْمَشْرِقِ يَوْمَئِذٍ مِنْ مُضَرَ مُخَالِفُونَ لَهُ.
