The Punishments....

(8:53) This happened because Allah is not one to change the favour which He has bestowed upon a people until they have changed their attitude. *40, Surely Allah is All-Hearing, All-Knowing.
*40. Unless a nation renders itself totally unworthy of God's favour, it is not deprived of it

(8:54)
Their case is like that of the people of Pharaoh and those before them: they rejected the signs of their Lord as false and so We destroyed them for their sins, and caused the people of Pharaoh to drown. For they were wrong-doers all.

(2:152) So remember ' Me and I will remember you, and give thanks to Me and be not ungrateful.

on your zakath....

2:264) O Believers, do not spoil your charity by taunts and injury to the recipients like the one who practises charity to be seen by men, while he neither believes in Allah nor in the Last Day. *303 His charity may be likened to the rainfall on a rock which had only a thin layer of soil upon it. When heavy rain fell on it, the whole of the soil washed away and the rock was left bare *304 Such people do not gain the reward they imagine they have earned by their seeming charity; Allah does not show the Right Way to the ungrateful . *305

303. The desire to display one's good deeds itself proves that the person concerned does not truly believe in God and the Hereafter. One who does good merely in order to impress people with his righteousness clearly regards those persons as his god. Such a person neither expects reward from God nor is he concerned that his good deeds will some day be reckoned to his credit.

*304. In this parable, 'heavy rain' signifies charity, and 'rock' the wicked intent and motive which lie behind external acts of charity. The expression, 'with a thin coating of earth upon it' signifies the external aspect of charity which conceals the wicked intent and motive of a man. These explanations make the significance and purport of the parable clear. The natural effect of rainfall should be the growth of plants and harvest. But if the earth, which is the repository of fertility, is insignificant in quantity, for example only a coating of it on some rock, the result will be that instead of yielding any beneficial result the rainfall may even prove harmful. Similarly, charity has the capacity to generate goodness and benevolence in human beings. Man's potential for goodness, however, is conditional on sincerity. Devoid of that charity leads to sheer loss and waste.

*305. Here the term kafir is used in the sense of the ungrateful person who refuses to acknowledge benevolence. People who either make use of the bounties of God in order to seek the gratitude of God's creatures rather than God's good pleasure, or who spend on others and then hurt them by stressing their acts of benevolence and kindness, are ungrateful to God for His bounties and favours. Since such people do not seek to please God, God does not care to direct them to the way that leads to His good pleasure
