Sayyiduna Bara’ bin Azib (may Allah be pleased with him) narrates: When the Prophet (peace and blessings of Allah be upon him) would lie down on his bed, he would place his right blessed hand under his right blessed cheek and would recite: “O Allah, save me from Your punishment on the day when You will resurrect Your servants.”
