Surah Al Ma'idah Tafseer

The Messenger's duty is but to convey. And Allah knows all that you reveal and all that you conceal.

This is a warning from Allah for His servants in which He says:

Our Messenger, whom We sent to you, has only to convey Our Message and then the reward for the obedience, and punishment for the disobedience is on Us. The obedience of those who accept Our Message never escapes Our knowledge, just as in the case of those who disobey and defy Our Message. We know what one of you does, demonstrates physically, announces, and utters with his tongue, and what you hide in your hearts, be it of faith, disbelief, certainty, doubt or hypocrisy. He Who is so capable, then nothing that the hearts conceal, nor any of the apparent acts of the souls in the heavens and earth could escape His knowledge.

In His Hand, alone, is the reward and punishment, and He is worthy to be feared, obeyed and never disobeyed
