After remaining patient for a while, Shahazada Qasim -asws went to see his mother and asked for an advice for getting permission to fight against the infidels.
Syeda Umm-e-Farwa -asws noticed signs of extreme emotions and zest in the eyes of her son and immediately reminded him the letter which his father gave to her -asws with instructions: “If ever you find Qasim -asws in severe difficulty, open this letter.” Syeda -asws asked Shahzada Qasim -asws ‘there would not be any compelling time than this, so take it out of your necklace and present it to your uncle -asws .’ Shahzada Qasim -asws opened the letter and it was written as, “My brother Hussain -asws , when my son Qasim -asws seeks your permission in Karbala, please accept him as a sacrifice on my behalf.” Hazrat Qasim -asws ’s face started to glow with the hope as if he was brought back to life.
He, without wasting any time, ran out of his mother’s tent to see his uncle -asws and gave him the letter. After reading the letter of his late brother, Imam Hussain -asws could not help but to cry and uttered, ‘O my brother’s son, how can I stop you from undertaking what your father had wised for you’. He was also my Imam -asws : Bismillah, go forward and perform your duty. Surely, Allah -azwj is with you.
Your grandfather -asws is eager to offer you a drink of Paradise when you greet him after meeting martyrdom”. Fight of Qasim -asws Ibn Hassan -asws Imam Hussain -asws torn the turban in two pieces and tied one on the head of Hazrat Qasim -asws and wrapped the other part on his face like a veil and said good bye . Imam -asws helped him mount his horse. Hazrat Qasim -asws came to the battlefield.
The army of Yazeed -la was stunned after seeing the ‘reincarnation’ of Imam Hassan -asws and Prophet Mohammed -saww , such a young and radiant face took their breath away and they started whispering ‘is he not an angel in the outfit of a beautiful and handsome boy?’ Some of them started murmuring, “How can we kill someone whose face is shining like the full-moon?” In a loud and a clear voice Hazrat Qasim -asws introduced himself and asked for a rival warrior to settle the battle of the ‘just’ against the ‘unjust’.
When Umar-e-saad -la [4] saw pure image of Imam Hassan -asws , he asked Arzaq -la (a famous warrior, who could fight against one thousand soldiers and could lift a baby camel as a shield) to advance and fight.
