CHARITY AND INTENTION

When a man goes to his wife so that he may be able to save his chastity, and protect his faith, he gets a recompense for his act.
Whatever he feeds his body, or whatever he does to sustain his wife and children, for that also he gets reward, provided there is goodness and righteousness in his intention.

Sa'ad Ibn Abi Waqas narrates that the Messenger of Allah has said: "If you spend even an ordinary thing for seeking the pleasure of Allah, you get its reward, so much so that even putting a morsel of food in the mouth of your wife is a virtuous act."

Another tradition has it:
"Whatever you feed your father, it is a charity from you. Whatever you feed your child, it is a means of reward for you, and whatever you feed your servant, it is also a charity from you."

The fact is that as long as man keeps himself as an obedient slave of Allah and his intention is pure and sincere, then all his acts and movements, his sleep and his walking are considered to be for seeking the pleasure of Allah.
