It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to make this supplication: 'Allahummaghfir lana dhunubana wa zulmana wa hazlana, wa jiddana wa 'amdana, wa kullu dhalika 'indana' (O Allah, forgive our sins, and pardon our wrongdoings, the things we said in jest, our seriousness and what we did deliberately, for all of these (weaknesses) are present in us). This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
