Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that when the Messenger of Allah (peace and blessings be upon him) raised his back from the bowing, he would say: 'Sami'a Allahu liman hamidah, Rabbana wa laka al-hamd' (Allah hears the one who praises Him; our Lord, and to You belongs all praise). Then he would supplicate for people, naming them by their names, and he would say: 'Allahumma anji al-Walid' "O Allah, save al-Walid bin al-Walid, and save Salamah bin Hisham, Ayyash bin Abi Rabi'ah and the weak among the believers. O Allah, tighten Your grip upon the disbelievers of Mudar and keep this punishment upon them for a long period." The people of the tribe of Mudar were at that time opposed to the Messenger of Allah (peace and blessings be upon him).
