Refuting the Disbelievers Who claim that They will be given Wealth and Children in the Hereafter

Imam Ahmad reported from Khabbab bin Al-Aratt that he said, "I was a blacksmith and Al-" ®256؛لs bin Wa'il owed me a debt. So I went to him to collect my debt from him. He said to me, `No, by Allah, I will not pay my debt to you until you disbelieve in Muhammad ﷺ.' I replied to him, `No, by Allah, I will not disbelieve in Muhammad ﷺ until you die and are resurrected again.' He then said to me, `Verily, if I die and am resurrected, and you come to me, I will also have abundance of wealth and children and I will repay you then.' Then, Allah revealed these Ayat,

أَفَرَأَيْتَ الَّذِى كَفَرَ بِـَايَـتِنَا وَقَالَ لأوتَيَنَّ مَالاً وَوَلَداً

This verse is an answer to ` As Ibn Wa’ ils boastful claim. How does he know that when he is brought back to life he will still have his wealth and children?

أَطَّلَعَ الْغَيْبَ (Has he peeped in the unseen - 19:78) It is obvious that nothing of this kind has happened. Then why has he considered it as a surety?
