89. Remember, O Messenger, the day when we will raise in every nation a Messenger who will testify against them about their denial or their acceptance of faith. This Messenger will be from their ownselves and will speak their language. We have brought you, O Messenger, as a witness against all communities. We revealed the Qur’ān to you to clarify everything that requires clarification such as the lawful and unlawful, reward and punishment etc. We also revealed it as a guidance for people to the truth, as a mercy to those who have faith in it and practice what it contains, and as good news for those who have faith in Allah of the everlasting bliss that awaits them.
