[BodeOmissemia]

When Pharaohs army marched into the desert behind Moses and trapped them badly, as in front of them was the sea, to their back was the avenging army.
when their ranks got panic, Moses allayed their fears by reminding them to keep the faith to continue trusting Allah who would not let them down. and Allah made them a way out through sea.

When Prophet PBUH and his companion Abu Bakr (r.z) took shelter in the cave of Thawr. and when he r.z feared people - discovering them, he r.z was asked by Prophet PBUH, Don't be afraid Allah is with us. Allah helped them miraculously with that spider web.

Allah was there in the Battle of Karbala too, why then Hussain and his companions were been martyred with dreadful wounds?
why were not they helped out? he had the strongest faith and Tawakkul AlalAllah indeed. And who has firm believe in Allah, he can never be harmed by anyone, Allah is there with them.
