It is narrated from Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no servant who performs a single prostration before Allah, the Mighty and Majestic, except that Allah Almighty raises him a degree by it and removes a sin from him because of it."
This hadith is narrated from Sayyiduna Ubadah (may Allah be pleased with him) only with this chain, and Khalid (may Allah have mercy on him) is alone in narrating it.
