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 ye who believe! Render not vain your almsgiving by reproach and injury, like him who spendeth his wealth only to be seen of men and believeth not in Allah and the Last Day. His likeness is as the likeness of a rock whereon is dust of earth; a rainstorm smiteth it, leaving it smooth and bare. They have no control of aught of that which they have gained. Allah guideth not the disbelieving folk.

O ye who believe! cancel not your charity by reminders of your generosity or by injury,- like those who spend their substance to be seen of men, but believe neither in Allah nor in the Last Day. They are in parable like a hard, barren rock, on which is a little soil: on it falls heavy rain, which leaves it (Just) a bare stone. They will be able to do nothing with aught they have earned. And Allah guideth not those who reject faith.
