When Allah fashioned Adam in Paradise, He left him as He liked him to leave. Then Iblis roamed round him to see what actually that was and when he found him hollow from within, he recognised that he had been created with a disposition that he would not have control over himself.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَمَّا صَوَّرَ اللَّهُ آدَمَ فِي الْجَنَّةِ تَرَكَهُ مَا شَاءَ اللَّهُ أَنْ يَتْرُكَهُ فَجَعَلَ إِبْلِيسُ يُطِيفُ بِهِ يَنْظُرُ مَا هُوَ فَلَمَّا رَآهُ أَجْوَفَ عَرَفَ أَنَّهُ خُلِقَ خَلْقًا لاَ يَتَمَالَكُ  

A hadith like this has been narrated on the authority of Humaid with the same chain of transmitters.  

حَدَّثَنَا حَمَّادٌ بِهَذَا الإِسْنَادِ نَحْوَهُ
