Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) narrates: I heard the Messenger of Allah (peace and blessings be upon him) making this supplication: 'Allahumma-ghfir li ma qaddamtu wa ma akhkhartu, wa ma asrartu wa ma a'lantu, wa ma anta a'lamu bihi minni, anta al-muqaddimu wa anta al-mu'akhkhiru, wa anta 'ala kulli shay'in qadir' (O Allah, forgive me the sins I committed before and those I committed after, those I committed in secret and those I committed openly, and also those which You know better than I do. You alone are the One who brings forward and You alone are the One who puts back, and You have full power over everything).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Nusayr bin al-Ash'ath except Anbasah, and his offspring (his grandson Muhammad bin Abd al-Wahid) is alone in narrating it from him."
