I was a blacksmith In the Pre-Islamic period of ignorance, and 'Asi bin Wail owed me some money. I went to him to demand it, but he said to me, "I will not pay you unless you reject faith in Muhammad." I replied, "By Allah, I will never disbelieve Muhammad till Allah let you die and then resurrect you." He said, "Then wait till I die and come to life again, for then I will be given property and offspring and will pay your right." So, thus revelation came: "Have you seen him who disbelieved in Our signs and yet says, 'I will be given property and offspring?' " (19.77)  

لاَ أَقْضِيكَ حَتَّى تَكْفُرَ بِمُحَمَّدٍ فَقُلْتُ لاَ وَاللَّهِ لاَ أَكْفُرُ بِمُحَمَّدٍ ﷺ حَتَّى يُمِيتَكَ اللَّهُ ثُمَّ يَبْعَثَكَ قَالَ فَدَعْنِي حَتَّى أَمُوتَ ثُمَّ أُبْعَثَ فَأُوتَى مَالاً وَوَلَدًا ثُمَّ أَقْضِيَكَ فَنَزَلَتْ {أَفَرَأَيْتَ الَّذِي كَفَرَ بِآيَاتِنَا وَقَالَ لأُوتَيَنَّ مَالاً وَوَلَدًا} الآيَةَ  

Khabbab said, "During the pre-lslamic period, I was a blacksmith and Al-Asi bin Wail owed me a debt." So Khabbab went to him to demand the debt. He said, "I will not give you (your due) till you disbelieve in Muhammad." Khabbab said, "By Allah, I shall not disbelieve in Muhammad till Allah makes you die and then resurrects you." Al-Asi said, "So leave me till I die and then be resurrected, for I will be given wealth and children whereupon I will pay you your debt." So this Verse was revealed:-- 'Have you seen him who disbelieved in Our Signs and, (yet) says: I shall certainly be given wealth and children.' (19.77)  

وَاللَّهِ لاَ أَكْفُرُ حَتَّى يُمِيتَكَ اللَّهُ ثُمَّ تُبْعَثَ قَالَ فَذَرْنِي حَتَّى أَمُوتَ ثُمَّ أُبْعَثَ فَسَوْفَ أُوتَى مَالاً وَوَلَدًا فَأَقْضِيكَ فَنَزَلَتْ هَذِهِ الآيَةُ {أَفَرَأَيْتَ الَّذِي كَفَرَ بِآيَاتِنَا وَقَالَ لأُوتَيَنَّ مَالاً وَوَلَدًا}
