باب {يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنْزِلَ إِلَيْكَ مِنْ رَبِّكَ}
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)
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 [quran sura="5" aya_start="67" aya_end="67"]{يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنْزِلَ إِلَيْكَ} الآيَةَ.
