Sayyiduna Abu Qatadah (may Allah be pleased with him) narrates: When the Prophet (peace and blessings of Allah be upon him) would camp at night during a journey, he would make his right hand a pillow. And when he would camp after the morning, he would raise his wrist and place his head on his palm.
