فَصَبْرٌ جَمِيلٌ ۖ وَٱللَّهُ ٱلْمُسْتَعَانُ عَلَىٰ مَا تَصِفُونَ
“Patience is most fitting. And Allah is the One sought for help against that which you describe.”
The verse Aisha RA recalled (misattributing it to "Abu Yusuf") when pressed by the Prophet ﷺ to respond.
“No blame will there be upon you today. Allah will forgive you.”
Quoted by the Prophet ﷺ of Yusuf AS, met in the 3rd heaven during al-Mi'raj (ep.021).
“That is from the stories of the unseen which We reveal to you [O Prophet]”
Cited (with Hud 11:49 and Al-Ankabut 29:48) to rebut a narrower objection -- that an unlettered 11-year-old could not have absorbed such detail -- rather than to vouch for the Buhayra account itself, which the lecture treats with real skepticism.
“And most people will not believe -- no matter how keen you are --”
Part of Surah Yusuf, which Allah revealed in full in response to the Quraysh's quiz (relayed via the Jews of Yathrib) about the family of Ya'qub AS -- see the DB event description; Yusuf 103's closing reflection that most people will not believe belongs to that same single-occasion revelation.
