أَفَمَن كَانَ عَلَىٰ بَيِّنَةٍۢ مِّن رَّبِّهِۦ كَمَن زُيِّنَ لَهُۥ سُوٓءُ عَمَلِهِۦ وَٱتَّبَعُوٓا۟ أَهْوَآءَهُم
Is he who relieth on a clear proof from his Lord like those for whom the evil that they do is beautified while they follow their own lusts?

Chapter: How the Divine Revelation used to be revealed and what was the first thing revealed
Narrated Abu `Uthman:
I was informed that Gabriel came to the Prophet (ﷺ) while Um Salama was with him. Gabriel started talking (to the Prophet). Then the Prophet (ﷺ) asked Um Salama, "Who is this?" She replied, "He is Dihya (al-Kalbi)." When Gabriel had left, Um Salama said, "By Allah, I did not take him for anybody other than him (i.e. Dihya) till I heard the sermon of the Prophet (ﷺ) wherein he informed about the news of Gabriel." The subnarrator asked Abu `Uthman: From whom have you heard that? Abu `Uthman said: From Usama bin Zaid.
