At the end of the verse Al-Anfal 8:36 ⧉, given there is the evil end of these people in terms of the Hereafter: وَالَّذِينَ كَفَرُوا إِلَىٰ جَهَنَّمَ يُحْشَرُونَ (And those who disbelieve shall be gathered into Jahannam).
In the verse under study, the mention of an evil end of spending wealth to stop people from following the true faith also includes the disbelievers of today who spend enormous wealth in the name of hospitals, educational institutions and charities only to stop people from following Islam and to attract them to their call for the false. Similarly, also included here are all those who have gone astray, those who spend their wealth to invite people to listen to doubts and superstitions they have generated into the established collective beliefs of Is-lam. But, Allah Ta`ala has His ways of keeping the faith revealed by Him protected. There are many occasions when it is openly noticed that such people fail to achieve their objective despite having spent huge amount of money and materials.
