I have children, one of whom attends to my needs, while the others do not inquire after me. As for the eldest, he does not return my Islamic greeting, even though he lives next door.

The questioner : I have children, one of whom attends to my needs and stands by me in every matter, while the others do not inquire after me. As for the eldest, he does not return my Islamic greeting, even though he lives next door. As for the younger one, he works in another city and does not visit me more than once in two years. I have some land. Is it permissible for me to give the one who is with me a portion of this land in exchange for his service to me, his standing by me, and his inquiring after me, since no one inquires after me after Allah (Mighty and Majestic) except him?

The Shaykh : I say: if he is working with you, and if he is doing so voluntarily seeking the reward of dutifulness, then do not give him anything.
As for if he is looking for you to give him something, then there is no blame on you in giving him a wage equal to what would be given to another person. For example, if this son were a stranger and not your son, and his monthly wage were five hundred riyals, then give him five hundred riyals, and there is no blame as long as he is working for you. Or give him a share of the profit equal to the amount of money he works with, like a foreign partner in a profit-sharing partnership.
As for the other two about whom you mentioned what you mentioned, I advise them to repent to Allah (Mighty and Majestic) and to be dutiful to their father. I fear for them the punishment in this world before the Hereafter. Whoever is dutiful to his father, his sons will be dutiful to him.
