People were free to practice their religion in Syria before the war. There were masjids, adhan, hijab; you could pray, fast, go on Hajj, etc. None of this was prevented. Students of Islamic knowledge from all around the world used to go to Syria to study. So tell me about the improvements the war has achieved?
The government is kafir, yes, and that is unacceptable; and if you want to change that, then you do it by a strategy that will actually work, and which will not devastate the society and make matters worse. If you cannot do that, then you bear with the situation, practice your Deen as best you can and have patience.
That is the ‘Aqeedah of Ahl us-Sunnah wal-Jama’ah.
Shaykh bin Baz said that while it is permissible, even obligatory to revolt against a kafir ruler, “if this is beyond their ability, they should not rebel. Also, if rebelling would result in worse evil, they should not do so to preserve the public interest.”
Shaykh Ibn Uthaymeen said, “Even if we were to assume the extreme – that a leader is a disbeliever – does this then mean we can incite the people to oppose him, even if it causes revolt, chaos, and killing? This is definitely wrong. The kind of rectification and improvement desired will never come by this approach. Rather, the only thing it will bring is great corruption”
If you do not see the destruction of Syrian society, the deaths of hundreds of thousands, the displacement of millions of Muslim men, women, and children, and the destabilization of the entire region, as a “great corruption”, a “worse evil” and against the “public interest”, then, quite simply, there is something psychologically wrong with you.
