After their return from Hudaibiya, the Muslims decided to conquer Khaiber in the 7th Hijra. 1700 soldiers were sent for this purpose. The ‘Hypocrites’ of Medina informed the people at Khaiber.

Three of the four forts were easily conquered.

One day Muhammad said that he would consign the flag to the person who kept Allah and his messenger as his friend. Many sahaba armed themselves and walked in front of the camp. Muhammad inquired about Ali. The Sahaba informed him that Ali could not take part because he had conjunctivitis.# [ ]

“The Holy Prophet(Sal’am) applied his saliva to his eyes which got cured for the whole of life”[ ]

#Mohammad gave him the flag and prayed To Allah for his success. Hazrat Ali killed some unbelievers. He was challenged by a Jewish wrestler named Merhab who was famous in all the areas  even in  Yemen and Syria.# [ ]

“Hazrat Ali  fell in wrath and struck at his head so forcefully that it came down leaving his back apart. When it became almost impossible to open the gate of the fort, Hazrat Ali came running his horse and moved the gate so strongly that it practically came to his hand and he threw it away raising up to head that the forces of Islam rushed into fort and started killing the non believers.” [ ]

#The people of the fort requested peace. They were willing to hand over their weapons and give every soldier a camel full of grain. Ali stopped the fighting. At the end forty youths could not lift the gate.
