"O Messenger (Muhammad ﷺ)! Proclaim (the Message) which has been sent down to you from your Lord..." (V.5:67)

Sahih al-Bukhari · Book 65 · Hadith 4612

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ إِسْمَاعِيلَ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَنْ حَدَّثَكَ أَنَّ مُحَمَّدًا صلى الله عليه وسلم كَتَمَ شَيْئًا مِمَّا أُنْزِلَ عَلَيْهِ، فَقَدْ كَذَبَ، وَاللَّهُ يَقُولُ ‏{‏يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنْزِلَ إِلَيْكَ‏}‏ الآيَةَ‏.‏

Narrated `Aisha: Whoever tells that Muhammad concealed part of what was revealed to him, is a liar, for Allah says:-- "O Apostle (Muhammad)! Proclaim (the Message) which has been sent down to you from your Lord." (5.67)
