Verses 1-5 Instructions have been given to the Prophet (PBUH) not to make something unlawful which God has made lawful. God gives expiation of oaths. Prophet gave a secret to a wife and she told it to the other. God revealed this to the prophet and He inquired that from her. Wives were instructed to repent other. God says that He is with Prophet (PBUH). Prophet (PBUH) has a protector Gabriel and other angels and helpers form the believers. If prophet divorces His wives, God will give him better than the present wives.
