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)
أَنَّ النَّبِيَّ ﷺ كَتَمَ شَيْئًا مِنَ الْوَحْىِ فَلاَ تُصَدِّقْهُ إِنَّ اللَّهَ تَعَالَى يَقُولُ {يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنْزِلَ إِلَيْكَ مِنْ رَبِّكَ وَإِنْ لَمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ}
