Quran 36:47 — Y.S. (Ya Sin)

وَإِذا قيلَ لَهُم أَنفِقوا مِمّا رَزَقَكُمُ اللَّهُ قالَ الَّذينَ كَفَروا لِلَّذينَ ءامَنوا أَنُطعِمُ مَن لَو يَشاءُ اللَّهُ أَطعَمَهُ إِن أَنتُم إِلّا فى ضَلٰلٍ مُبينٍ

When they are told, "Give from GOD's provisions to you," those who disbelieve say to those who believe, "Why should we give to those whom GOD could feed, if He so willed? You are really far astray."

[36:46] No matter what kind of proof is given to them from their Lord, they consistently disregard it.

[36:48] They also challenge, "When will that promise come to pass, if you are truthful?"
