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! 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.
