Spendthrifts

Chapter 17 The Holy Qur’an

26. And render to the kindred their due rights, as (also) to those in want, and to the wayfarer: But squander not (your wealth) in the manner of a spendthrift. 27. Verily spendthrifts are brothers of the Evil Ones; and the Evil One is to his Lord (himself) ungrateful.

Re: Spendthrifts

A spendthrift (also called profligate) is someone who spends money prodigiously and who is extravagant and recklessly wasteful. The origin of the word is someone who is able to spend money acquired by the thrift of predecessors or ancestors.
