It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to recite this supplication between the two prostrations in the night prayer: "Rabbighfir li, warhamni, warfa‘ni, warzuqni, wahdini." (O my Lord! Forgive me, have mercy on me, elevate me, provide for me, and guide me.)
