“ And Allah knows your deeds.
31 And certainly We shall try you, till We know those among you who strive hard, and the steadfast, and manifest your news.
32 Surely those who disbelieve and hinder (men) from Allah's way and oppose the Messenger after guidance is quite clear to them, cannot harm Allah in any way, and He will make their deeds fruitless.
33 O you who believe, obey Allah and obey the Messenger and make not your deeds vain.
34 Surely those who disbelieve and hinder (men) from Allah's way, then die disbelievers, Allah will not forgive them. ”

“ And if Allah please, He would certainly exact retribution from them, but that He may try some of you by means of others. And those who are slain in the way of Allah, He will never allow their deeds to perish. ”
