Sayyiduna Anas (may Allah be pleased with him) narrates: Sayyiduna Zaid bin Harithah (may Allah be pleased with him) came and complained to the Prophet Muhammad (peace and blessings be upon him) about (his wife) Sayyidah Zainab (may Allah be pleased with her). The Prophet Muhammad (peace and blessings be upon him) said: "Keep your wife with you (i.e., do not divorce her)." So regarding this, the following verse was revealed: "You were concealing within yourself that which Allah was to disclose."
