Al-Baqarah 2:264 يا ايها الذين امنوا لا تبطلوا صدقاتكم بالمن والاذى كالذي ينفق ماله رياء الناس ولا يومن بالله واليوم الاخر فمثله كمثل صفوان عليه تراب فاصابه وابل فتركه صلدا لا يقدرون على شيء مما كسبوا والله لا يهدي القوم الكافرين ٢٦٤

O you who believe! Do not render in vain your Sadaqah (charity) by reminders of your generosity or by injury, like him who spends his wealth to be seen of men, and he does not believe in Allâh, nor in the Last Day. His likeness is the likeness of a smooth rock on which is a little dust; on it falls heavy rain which leaves it bare. They are not able to do anything with what they have earned. And Allâh does not guide the disbelieving people.
