There was once a rich old man who did not like to give his money to charity.
He had a good son who always told his dad that he should give his money in the way of Allah.
The old man told his son that he could give it all away after his death
The son told him that it would be too late for the father, for he should give it away now to be able to get the benefits in the hereafter (grave and onwards).
The old man just would not listen.
One night the old man wanted to go out. It was very dark so he asked his son to carry a lamp and walk in front of him so he would be able to see.
The son obeyed his father but half way he started walking behind his dad.
His father said:
"Why have you gone behind me?" I can't see! I need the lamp in front."
The son said:
"Father! that's exactly what i have been telling you. If you want light in the grave you have to give away what you have in the way of Allah before you die and not after."
The old man finally understood what his son had been trying to tell him!
