shaking hands with non muslims doesn't prove kufr, that's a pretty narrow way to look at things. how exactly is he supposed to go about it in the world we live in today threaten to kill them? sometimes you need to compromise for the sake of other people or at least save your threats until you have some sort of power base to threaten from. sheik sharif understands that and that's why he has continuosly asked for every group to bring something to the peace process and this says alot about his character, the fact that al shabaab continues on with pointless fighting irregradless of the suffering it is causing says alot about them.
anyways the only way you can fight a muslim goverment is if the goverment is seriously off the right path ignoring the quran or sunnah or insulting the quran and sunnah or neglecting the fundamentals of islam.
the fact that every single group in somalia is opposed to this group says alot about them and should serve as a warning to those who support them.
salaam
you have put across a straw man argument, did i say he was a kaffir because he shook hands with them?
no i said he was a kaffir for allying with them, taking as his allies the same who are fighting the believers the world over.
do you agree alliance with the kuffar who are warring with the believers is a form of kufr akbar, and kufr known by necessity?
Ibn Hazm Stated in Al-Muhalla (11/138):
"What is correct is that His statement, the Most High, "And if any amongst you takes them as Auliya', then surely he is one of them." (The Quran 5:51), should be understood on the basis of its apparent meaning. The person being referred to is a disbeliever from the generality of disbelievers, and no two Muslims disagree regarding this."
Sheikh Muhammad ibn Abdul Wahab, may Allah have mercy on him, gathered ten actions that negate one's Islam (Nawaqid ul-'Ashr), the eighth one of which states:
"Assisting the disbelievers (against the believers) (Mudhaharatul Mushrikeen) and supporting them against the believers (is from the actions that negates of one's faith). The Proof being the statement of Allah, "And if any amongst you takes them as Auliya', then surely he is one of them. Verily, Allah guides not those people who are the Zalimun (polytheists and wrong-doers and unjust). (The Quran 5:51)."
Sheikh Abdul Latif bin Abdur Rahman bin Hassan Aal-Sheikh, may Allah have mercy on him stated (Ad-Durrar 8/326):
"Whosoever helps the disbelievers or draws them to the country of Ahl Al-Islam (People of Islam), then such is a manifest apostate by consensus."
Sheikh Abdullah ibn Humaid may Allah have mercy on him, stated(Ad-Durrar 15/479):
"Whoever expresses Tawalli [2] towards the disbelievers (Tawalli Kuffar) and supports and helps them against the believers, then such constitutes apostasy by one's (proceeding) actions. It is obligatory to apply the rules of apostasy upon such a person as is proved by the book, the sunnah and the consensus of the scholars.
Sheikh Ibn Baz stated (Al-Fatawa 1/274):
"There is a consensus amongst the scholars that whoever supports the disbelievers against the believers (Dhahar Al-Kuffar 'Ala Al-Muslimeen), and assists them by any means of assistance, then he is a disbeliever just like them (the disbelievers he supported)…"
