Re: "We wanted to kill shias with Cyanide"
i've said it already. Quran (because no one argues on that). Hadith (because everyone believe Prophet Muhammad (PBUH) as being the last prophet and his way of living the ideal for us to follow).
It's not as complicated as our ancestors have made it out to be. And we're only carrying the differences with us. We're not really serving Islam. There were no sects at the time of beloved Prophet. Then why now?
I believe we (the muslims) have to go back to the guides that have been handed to us as genuine and ultimates guides. Quran and Hadith.
When we start to read Quran, love one another because we're all muslims regardless of our minor differences, then these differences will inshaAllah disappear and Allah will put Barakah in all our affairs.
The muslim ummah at the moment is like a bundle of sticks that's been separated and every stick is vulnerable to breaking and shattering. If we regather and become one again, we'll be strong just as we once were. And we will inshaAllah, sooner or later. The sooner the better.
