Atiyyah said that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) supplicated in this way: "O Allah, forgive us, have mercy on us, grant us well-being, guide us and provide for us."

Yahya bin Rashid said: We performed Hajj, and when we had completed our rites we said: "If we were to go to Sayyiduna Ibn Umar (may Allah be pleased with them both), he would narrate some hadith to us." So we went to him, and he came out to us and sat among us. He remained silent so that we might ask him, and we remained silent so that he might narrate hadith to us. When the silence grew long, he said: "What is the matter with you, that you do not speak? Will you not recite these words: Allah is free of every defect, all praise is for Allah, there is no god but Allah, Allah is the Greatest, and there is no power to avoid sins and no strength to do good except with the help of Allah? The reward of a good deed is from ten times up to seven hundred times, and if you increase in good, Allah will also give you greater reward."

Meaning that he said these words while in the bowing position.
