And a proclamation from Allah and His messenger to all men on the day of the Greater Pilgrimage that Allah is free from obligation to the idolaters, and (so is) His messenger. So, if ye repent, it will be better for you; but if ye are averse, then know that ye cannot escape Allah. Give tidings (O Muhammad) of a painful doom to those who disbelieve,

Chapter: “O Messenger! Proclaim which has been sent down to you from your Lord. And if you do not, then you have not conveyed His Message…”
Narrated `Aisha:
Whoever tells you that the Prophet (ﷺ) concealed something of the Divine Inspiration, do not believe him, for Allah said: 'O Apostle Muhammad! Proclaim (the Message) which has been sent down to you from your Lord, and if you do it not, then you have not conveyed His Message.' (5.67)
