Mishkat al-Masabih 2363

‘Abd Allah ibn Mas‘ud reported that the Messenger of God (peace be upon him) said: ‘One who repents from a sin is like one who has no sin.’ Ibn Majah and al-Bayhaqi in Shu‘ab al-Iman transmitted it. Al-Bayhaqi said: ‘Al-Nahrani alone transmitted it, and he is unknown.’ Sharh al-Sunnah also reports it from Ibn Mas‘ud in mawquf form: ‘Regret is repentance, and the one who repents is like one who has no sin.’ The Arabic source marks it as not studied by al-Albani.
