Kharijah bin Zayd (may Allah have mercy on him) said: I heard Sayyiduna Zayd bin Thabit (may Allah be pleased with him) saying that this verse of Surah al-Nisa, 'And whoever kills a believer intentionally' [Surah al-Nisa: 93], was revealed six months after the verse of Surah al-Furqan, 'And those who do not call upon another god along with Allah' [Surah al-Furqan: 68].
The Shaykh said: The revelation was indeed thus, but the interpretation will be in accordance with the verse of Surah al-Furqan.
