The Coalition - 33:19
They are stingy in their dealings with you. When danger comes, you see them looking at you with their eyes wide with fear, like one who has fallen into a faint of death. And when the danger passes, they hurt you with sharp tongues, being fond of wealth. Such people are not believers. That is why Allah makes their deeds vain. This is easy for Allah.
The hypocrites are stingy in their dealings with the believers:
The Repentance/9:74
Although they speak words of disbelief and disbelieve after they have surrendered, they swear by Allah that they did not say them. In fact, they strived hard for what they could never attain. They sought revenge after Allah and His messenger had enriched them with His grace! It would be good for them if they repent. If they turn away, Allah will punish them with a painful torment in this world and in the Hereafter, and they will have neither friends nor helpers in the earth.
The Repentance/9:75
"Some of them even promised Allah, "If He grants us out of His bounty, we will spend our money for charity and we will be of the righteous people."
The Repentance/9:76
But when He gave them out of His bounty, they became stingy and turned away.
The Repentance/9:77
Because they broke their promise to Allah and lied, He put hypocrisy in their hearts until the Day when they will meet Him.
The Repentance/9:97
The Arabs are the most extreme in disbelief and hypocrisy. They are the closest to not recognizing what Allah has revealed to His Messenger. Allah is All-Knowing, All-Wise.
The Repentance/9:98
Some of the Arabs consider their help a loss and a burden, and they look for calamities for you. The worst calamities are for them. Allah is All-Hearing, All-Knowing.
