Sayyiduna Khabbab (may Allah be pleased with him) narrates: I was a blacksmith in Makkah. I made a sword for ‘As bin Wa’il. I went to him to demand (the price for it), so he said: I will not pay you until you disbelieve in Muhammad (peace be upon him). I said: I will not disbelieve in Muhammad (peace be upon him) until Allah gives you life again. He said: When Allah gives me death and then brings me back to life, at that time I will have wealth and children, so I will pay you. (Sayyiduna Khabbab, may Allah be pleased with him, narrates) I mentioned this to the Prophet (peace be upon him), so Allah revealed this verse:“Have you seen the one who disbelieves in Our verses and says: I will surely be given wealth and children?”

(Imam Ibn Hibban, may Allah have mercy on him, says:) If the hearts of those who hear these words are inclined towards this—meaning these words that I made a sword for ‘As bin Wa’il and then I went to him to demand (its price)—(so the listener thinks) that trading in Dar al-Harb is permissible and that it is permissible for a Muslim to buy and sell with a Harbi, as long as he benefits the Muslims with its price, then it should be known that this is a weak deduction and a harmful argument. The reason is that when Sayyiduna Khabbab (may Allah be pleased with him) made this sword for ‘As bin Wa’il, at that time Allah had not revealed the verse regarding the command of fighting, nor had jihad been made obligatory. The reason is that the obligation of jihad and the command to fight the polytheists was revealed after the Prophet (peace be upon him) left Makkah, as we have mentioned earlier, and this incident of Sayyiduna Khabbab (may Allah be pleased with him) is from Makkah, which is before Allah made jihad obligatory upon the people.
