Mu'jam Kabir Tabarani 4886 — (and he was a truthful man) that we were

Awf bin Mujalid al-Hadrami (may Allah have mercy on him) narrates (and he was a truthful man) that we were with Kharijah bin Zayd bin Thabit (may Allah have mercy on him), and he related that I said to Sayyiduna Zayd bin Thabit (may Allah be pleased with him): O Abu Sa'id, we find in Surah al-Furqan: "And those who do not invoke any other deity along with Allah, nor kill a soul which Allah has made sacred except by right, nor commit adultery" [al-Furqan: 68], up to the end of the verse: "And Allah is Forgiving, Merciful" [al-Nisa: 96]; and we find in Surah al-Nisa: "And whoever kills a believer intentionally, his recompense is Hell, abiding therein forever, and Allah is angry with him, has cursed him and has prepared for him a great punishment" [al-Nisa: 93]. So in one verse we find room for repentance from this sin, and in the other we find a severe threat without any exception. Sayyiduna Zayd bin Thabit (may Allah be pleased with him) said: "This severe verse was revealed six months after this lenient verse, so the severe verse abrogated the lenient verse."
