Praise be to Allaah.
If you have a question about any matter of religion, you must ask the people of knowledge, as Allaah says (interpretation of the meaning):
“So ask the people of the Reminder if you do not know” [al-Anbiyaa’ 21:7]
If you are given a fatwa by someone whose knowledge and taqwaa you trust, then you have to adhere to that fatwa. It is not permissible for a person to ask a number of scholars so that he can choose the easiest fatwa or whatever suits his desires or opinion.
