IT IS A FAULT TO SAY AND NOT DO
Most people talk and talk but do not act. Or they give hope, say something and give a promise to people, but do not do it. It does not go for nothing and Allah will question it. If you are unable to do it you do not need to say it, but if you say it you have to do it. Do not say it if you cannot do it. You are being trusted and you are turning the trust into a disappointment and aggrieving people. Therefore, do it if something is to be done and you give a promise. If you are to speak, stand behind it like a man. Stand behind your word and if you will not be able to do it then do not do it.
