The Disbelievers spend Their Wealth to hinder Others from Allah's Path, but this will only cause Them Grief

Muhammad bin Ishaq narrated that Az-Zuhri, Muhammad bin Yahya bin Hibban, `Asim bin `Umar bin Qatadah, and Al-Husayn bin `Abdur-Rahman bin `Amr bin Sa`id bin Mu`adh said, "The Quraysh suffered defeat at Badr and their forces went back to Makkah, while Abu Sufyan went back with the caravan intact. This is when `Abdullah bin Abi Rabi`ah, `Ikrimah bin Abi Jahl, Safwan bin Umayyah and other men from Quraysh who lost their fathers, sons or brothers in Badr, went to Abu Sufyan bin Harb. They said to him, and to those among the Quraysh who had wealth in that caravan, `O people of Quraysh! Muhammad has grieved you and killed the chiefs among you. Therefore, help us with this wealth so that we can fight him, it may be that we will avenge our losses.' They agreed."

The word, الْخَبِيثَ al-khabith, is used to refer to that which is impure, filthy and forbidden while الطَّيِّبِ at-taiyyib set against it denotes what is pure, clean, nice and lawful. At this place, the use of these two words may be referring to the impure possessions of the dis-believers, and the pure possessions of Muslim as well. Given this projection, it would mean that the enormous wealth spent by the disbelievers was impure and filthy. The evil end it met was that they suffered the loss of wealth, and the loss of lives as well. As compared to them, Muslims spent very little of whatever they had in the name of wealth, but that wealth was pure and lawful. Those who spent it succeeded, not to mention the additional spoils of war that fell into their hand. After that, it was said:
