وعليكم سلام ورحمة الله وبركاته With regards to doing Hijra to Muslim countries , it is obligatory in Islam but only for those who are able to do so as it is like the rest of the obligations in Islam which are obligatory only upon those who have the ability. I advise the brothers with what Shayk Muqbil رحمه الله used to advise with regards to making Hijra. It is that whoever wants to do Hijra should not do so directly. Rather he should first stay in those Islamic countries and see whether he can stay there permanently thereby making it as a Hijra . As for Yemen , there is goodness and Salafi Dawah is going good here. But it is currently a country in which there is war going on in its North , and therefore it is necessary to think more , look and search from all angles before one makes the decision of doing Hijra , and whoever wants to enter it should settle in its South. However he must enter the country in a legal way and should obtain a valid residence and so on so as not to go against the ruler on one hand and to be safe on the other hand since the situation there is changing rapidly . Likewise , I advise him to choose for himself a good place where there are Salafis and the teacher should be a useful brother far from Fitan busying himself in spreading knowledge and benefitting the people around him.
