It is narrated from Sayyiduna Suhaib (may Allah be pleased with him) that indeed the Messenger of Allah (peace and blessings be upon him) was moving his lips during the days of Khaybar. He was asked, "What supplication are you making?" He replied: "I am saying: (O Allah!) I walk and move about only with Your help, I fight only with Your help, and I attack only with Your help."
