It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) would wake up in the middle of the night to pray, he would recite this supplication. Then the narrator mentioned the complete supplication and also said: Your word is true, Your promise is true, meeting You is true, forgive all my past and future, hidden and apparent sins. You are my Lord, there is no deity except You.
