And let not those who [greedily] withhold what Allah has given them of His bounty ever think that it is better for them. Rather, it is worse for them. Their necks will be encircled by what they withheld on the Day of Resurrection. And to Allah belongs the heritage of the heavens and the earth. And Allah , with what you do, is [fully] Acquainted.
[Qur’aan 3:180]
**It was narrated from Abu Hurairah that the Prophet said:
"If Allah gives a person wealth and he does not pay Zakah on it, his wealth will appear to him on the Day of Resurrection as a bald-heated Shuja’a with two dots above its eyes. It will take hold of the corners of his mouth on the Day of Resurrection and will say: ‘I am your wealth, I am your hoarded treasure.’
The he recited this verse: ‘And let not those who covetously withhold of that which Allah has bestowed on them of His Bounty (wealth) and think that it is good for them (and so they do not pay the obligatory Zakah)."’**
