Salam aleikum rahmatullah wa barrakatuh I am familiar with the abrogation of verses in the holy Quran. But I came across this hadith resently: "There was revealed about those who were killed at Bi’r-Ma’una a Qur’anic Verse we used to recite, but it was cancelled later on. The verse was: ‘Inform our people that we have met our Lord. He is pleased with us and He has made us pleased.’" Bukhari vol.4 book 52 ch.19 no.69 p.53." Can someone explain it. Is it really true that the Quran has had a cancelled verse and are it more cancelled verses? Can someone with knowledge give me an answer? And explain more of this hadith, is it really trusthworthy despite it is from Bukhari?
