It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) had prayed and finished his prayer, he would wipe his head with his right hand and say: 'Bismillahi alladhi la ilaha illa huwa al-Rahman al-Rahim, Allahumma adhhib 'anni al-hamma wal-hazan' (In the name of Allah, besides whom there is no god worthy of worship, the Most Gracious, the Most Merciful; O Allah, remove from me worry and grief).
