Praise be to Allaah.
The Muslim should turn to Allaah at times of ease and at times of hardship, and seek the help of Allaah in all his affairs, as Allaah says (interpretation of the meaning):
“Is not He (better than your gods) Who responds to the distressed one, when he calls Him, and Who removes the evil…” [al-Naml 27:62]
If a person calls on his mother or anyone else to help him in a matter in which that person is able to help, then this is permissible. So long as a person is alive, present and able, there is nothing wrong with seeking his help, but it is better and preferable to ask Allaah for help in all circumstances. And Allaah is Able to do all things.
