(V.3:180) "Let not those who covetously withhold of that which Allâh has bestowed upon them of His Bounty ... shall be tied to their necks like a collar."
Narrated Abu Hurairah رضي الله عنه: Allâh’s Messenger (صلى الله عليه وسلم) said, "Anyone whom Allâh has given wealth but he does not pay its Zakât; then, on the Day of Resurrection, his wealth will be presented to him in the shape of a bald-headed poisonous male snake with two poisonous glands* in its mouth and it will encircle itself round his neck and bite him over his cheeks and say, ‘I am your wealth; I am your treasure.’" Then the Prophet صلى الله عليه وسلم recited this Divine Verse: "And let not those who covetously withhold of that which Allâh has bestowed upon them of His Bounty." (V.3:180).
