What is obligatory for my brother, given that he will be forced either to remain in Turkey, with all its forbidden matters, or to perform military service in Syria?

The Shaykh : Standing. Still standing.
The student: Yes.

The Shaykh : Okay, so the question is that he cannot leave at all.
The student : Yes, he will be forced either to perform military service or to remain in Turkey, with all its forbidden matters.

The Shaykh : Here comes a very important jurisprudential rule, which is: "When a Muslim is caught between two harms, he chooses the lesser of them." Between two evils, he chooses the lighter one, and so on. The one who is afflicted with residing in Turkey can weigh the harms that befall him due to this Turkish residence against the harms that occur to him in the Syrian residence under forced service. If remaining in Turkey appears to him to be the lesser of the two, he remains in Turkey. This is what I think from a distance, but I do not issue a ruling on it.
The student : May Allah reward you with good.

The Shaykh : And do not drink cold water, or tea, or whatever.
The student : May Allah reward you with good and honor you. Brother 'Ammar has a topic with the system. An old topic, somewhat.

The Shaykh : Yes, but you do not want to deviate from my answer.
The student : Because it was facilitated for them.

The Shaykh : Now, just say it.
The student : May Allah reward you with good.
