I agree with you, I didn't find any joy or reason to celebrate in this or the other murders either.
It terrifies me that the Ummah behaves like this, what are we a pack of animals?
And when the hour comes how are we meant to ask Allah for compassion and mercy when we do not show his creation the same?
I've heard all the reasons; the oh they did xy & z they deserved it, but honestly when it comes down to it, we are not the ones who are elected to punish those who we perceive as guilty, otherwise what is the point of having a judicial system.
And how can one Muslim countenance killing another? How?
I feel so utterly shocked by it all and so sad...any good that these people did they now have the beating and murdering of a defenseless 70 year old man on their hands. It doesn't take a big person to take out an unarmed old man hiding in the gutter.
I was thinking about this recently and listening to Surah Ad Duha & I decided that I forgive anyone in my life anything I possibly hold a grudge against them for, I pray Allah safeguard me from ever becoming the oppressor or that which I despise.
