Allah's Bounty
Those who hoard wealth and refuse to spend in Allah’s cause should not think it is good for them. Rather, it will be a burden around their necks on the Day of Judgment.
3:180And let not those who hoard up that which Allah hath bestowed upon them of His bounty think that it is better for them. Nay, it is worse for them. That which they hoard will be their collar on the Day of Resurrection. Allah's is the heritage of the heavens and the earth, and Allah is Informed of what ye do.
