Blessed is he who discharges his obligations towards Allāh and endures his hardships, allows himself no sleep in the night but when sleep overpowers him lies down on the ground using his hand as a pillow, along with those who keep their eyes wakeful in fear of the Day of judgement, whose bodies are ever away froth beds, whose lips are humming in remembrance of Allāh and whose sins have been erased through their prolonged beseechings for forgiveness. They are the party of Allāh; Be it known, verily the party of Allāh alone shall be the successful ones (Qur’ān, 58:22).
