Oh my, Omran, ow! I'm glad your hand is healing. This is a very good thread for people to read, though.
I would add maybe two more safety rules:
-- don't do something dangerous just because 'it'll only be this one time' and you're in a hurry or lazy; and
-- clamp the workpiece unless it's real big and you're standing on it; and use an extra sawhorse or two to support the cutoff so that it does not sag as it begins to be cut free, and bind the sawblade, and cause emergency room visits.
