Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) relates: In the time of the Prophet (peace and blessings be upon him) we recited this verse in this way for two years: "And those who do not call upon another god along with Allah, nor kill a soul which Allah has made sacred except by right, nor commit adultery" [Surah al-Furqan: 68] to the end of the verse. Then this was revealed: "Except whoever repents" [Surah Maryam: 60]. I never saw the Prophet (peace and blessings be upon him) more joyful at anything than at that, and likewise at this verse: "Indeed, We have granted you a clear victory" [Surah al-Fath: 1].
