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)
