From amongst these ayat is His statement,
“Indeed, those who believe – never will their wealth or their children avail them against Allah at all, and those are the companions of the Fire, they will abide therein eternally. The example of what they spend in this worldly life is like that of a wind containing frost which strikes the harvest of a people who have wronged themselves and destroys it. And Allah has not wronged them but they wronged themselves.” (Surah Ali-Imran:116-117)
Here, Allah has set an example of those who spend their wealth in matters displeasing to Allah. He likened the wealth that they spend to showing off and gaining the praise of people – so they lead them away from the way of Allah and His Messengers – to seeds that one planted in the hope of achieving benefit, but then a windstorm containing frost strikes the harvest, leaving it withered and destroyed. Scholars offered three meanings of the Arabic word “Sirr” that has been used in this ayah to describe the wind. Some said it is extreme coldness, others such as Ibn Abbas said it is fire.
Al-Anbari said the reason why fire is described as “Sirr” is due to its sound when it burns. Some others said “Sirr” is the sound accompanying a windstorm as a result of its extreme power and speed. The three statements are all correct and related because it is extreme cold that burns the harvest, leaving it dry, similar to how fire burns and it also blows with a powerful noise.
The phrase ”strikes the harvest of a people who have wronged themselves’‘ is to notify us of their wrongdoings for which the windstorm struck their harvest in the first place. The wrongdoing of the people was the windstorm that destroyed their good deeds and spending.
