Q: Isn't it Haram (forbiden) to be a part in elections in a non-islamic state?
The evidence from the salaf that we follow is what the scholars used to do before, when they used to go to the leaders of their time (note: many of these leaders was worse than many nowaday rulers !), they go to make naseeha (advice) and forbid them from evil. The Ikhwan's objective from the parliament is to try to forbid evil as much as they can. You may say: "But this is a non-Islamic regime", and that is true that the regime there is NOT A TRUE Islamic regime, but the point is: Is it a "kaffir" regime in order not to forbid getting involved in any of its systems ? The answer is that those guies ruling a country like Egypt are not "kaffirs" but they are "sinners", and we (as a group) are not judges on the Iman of people as long as they declair Islam, but rather invitors to the way of Allah (s) [Refer to the book "Du3ah la Qudah" (Invitors and not Judges) by Os.\ Hassan Al-Hodeibi, the ex-leader of Al-Ikhwan].
And then, does the elections mean a confess that the current law is correct from the Islamic point of view and that it is now the constitution of Al-Ikhwan???? Absolutely not. Al-Ikhwan said that: "We are a part of that society, and so we are doing what is within our capability to change un-Islamic laws in all aspects of life for the good of this society". Moreover, professional or social organizations is a completely different story. These organizations are not applying non-Islamic laws !! nor their leaders are governing with the laws of Islamic Shari'a. The situation here is, also, different. Even if there are some rules in their by-laws which are Haram, they can be easily changed according to the elected board.
I truly FEAR that Islam is on a parallell to what McCarthy exposed!
