o believers do not spoil your charity by taunts and injury to the recipients like the one who practises charity to be seen by men while he neither believes in allah nor in the last day. his charity may be likened to the rainfall on a rock which had only a thin layer of soil upon it. when heavy rain fell on it the whole of the soil washed away and the rock was left bare such people do not gain the reward they imagine they have earned by their seeming charity allah does not show the right way to the ungrateful.
يا أيها الذين آمنوا لا تبطلوا صدقاتكم بالمن والأذى كالذي ينفق ماله رئاء الناس ولا يؤمن بالله واليوم الآخر فمثله كمثل صفوان عليه تراب فأصابه وابل فتركه صلدا لا يقدرون على شيء مما كسبوا والله لا يهدي القوم الكافرين
