No way! Allahu alam...I was referring to taking help from Non Muslims to fight Non Muslims themselves.why do Muslims need to take help from non Muslims to fight Muslims? That is of course wrong. However if a Muslim was to do acts against the Quran and Sunnah, that then takes him out of the fold of Islam, and if he/they were to fight against the Muslims then taking help from the Non Muslims to fight them will not be haram cos they were then not Muslims either.
