Musannaf Ibn Abi Shaybah 34502 — Reports on Ibn Rawahah

Qays (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him): "Why do you not urge on our mounts?" Abdullah (may Allah be pleased with him) said: "I have given up my poetry." Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: "Listen and obey." So he (may Allah be pleased with him) dismounted and began driving the mount of the Prophet of Allah (peace and blessings be upon him), reciting these verses: "O Allah, were it not for You we would not have been guided, nor would we have given charity, nor would we have prayed. So send down tranquility and mercy upon us, and make our feet firm if we meet the enemy. Indeed, the disbelievers have transgressed against us." At this the Messenger of Allah (peace and blessings be upon him) said: "O Allah, have mercy on him." Sayyiduna Umar (may Allah be pleased with him) said: "Paradise has become certain for him."
