It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to recite this supplication while sitting between the two prostrations during the night prayer: «رَبِّ اغْفِرْ لِي وَارْحَمْنِي وَارْفَعْنِي وَارْزُقْنِي وَاهْدِنِي» "O Lord! Forgive me, have mercy on me, raise my ranks, grant me sustenance, and guide me." Then he would perform the second prostration.
