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 have believed, do not invalidate your charities with reminders [of it] or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allāh and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allāh does not guide the disbelieving people.
