ANSWER:
As Muslims, we all love to free Syria from the Tyrant Nosairi ruler and his regain. The problem is that all foreigners who go there either end up sold to foreign intelligence agencies or engaged in internal fighting over power, leaving Islam behind their back!
There’s no single muslim flag or a muslim leader under whom we can go and fight. Six or seven factions there all claim to be Muslims and all killing one another and accusing others of kufr. Those who label Muslim in general and their rulers in particular are khawarij. Those in your country who encourage people to go and fight when the harm is far greater than any benefit for the Muslims are also khawarij as they give takfeer to Muslims without any knowledge or scholars backing them! The Prophet salla Allahu Alaihi wa salah had described them as the hounds of Hell.
