Shaykh ‘Ubayd Al-Jaabiree
Question: May Allaah reward you with good and treat you well. Another questioner adds emphasis to the previous question and says: Is it permissible to deal with the Hizbees in worldly affairs, such as trading? For some of the youth do that and they say: I do not deal with them except in worldly affairs!
Answer: I say: If you are able to stay far away from the innovators so that you do not share with them in any activity, religious or worldly, then do so.
As for religious activities, they are referred to as Da’wah based activities; then do not accommodate them and do not help them in building Masaajid by which innovation is spread, nor schools by which innovation is spread, nor in printing books in which innovation is spread; never. Because, he who helps them while he knows their condition, then he is like them, whether intentionally or unintentionally.
As for worldly affairs: When you are in need of that and the man from amongst you is strongly fortified in the correct ‘Aqeedah and strongly fortified in the Sunnah and strongly fortified in warning against innovation; and he is in need of dealing with these people, then there is nothing to prevent that, as long as that is in accordance with the level of his need; and let him beware of mixing with them. Allaah’s Messenger صلى الله عليه و سلم said:
“A man is upon the Deen of his intimate friend; so let one of you look to whom he befriends.”
So this is a dangerous affair. How many a man was swept away by affairs of the Dunyaa, until he became detached and became an enemy of the Sunnah and its people or one who had a dead sense of religious jealousy, having no Walaa or Baraa’ for the sake of Allaah.
If you want to deal with the innovator in order to employ him, and you are the one in charge and you are the watcher over him, there is no doubt that this is safer. And if you need to work with him then beware of him and let your dealings with him be worldly dealings only. “Take a Deenaar and give me a Deenaar;” only. “The price of this is so and so; the price of that is so and so.” And do not get comfortable and enter with him to the point that he drags you to dealings in the religion, or Da’wah based dealings.
If you are able to suffice without him (and deal) with each other, O group of Salafees, then this is safer for your religion and your honor. This is what we encourage you upon and call you to. That which is more beloved to us is that you do without the Hizbees, revolutionaries, and all of the people of innovation.
