It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) visited a sick person, he would sit by his head and recite this supplication seven times: 'As'alu Allaha al-'Azima Rabba al-'Arshi al-'Azimi an yashfiyak' (I ask Allah the Magnificent, Lord of the Magnificent Throne, to grant you healing). If there was still some respite in his appointed term, he would recover from that illness.
