There was a moat surrounding the fortress. Hazrat Ali had been unable to accompany the Muslims due to his illness. Three days passed and the Muslims could not find any solution. Even if they got across the moat they would face the famous gates of the fortress.
These were made of steel, and it is said that at least twenty men were needed to push open or close each gate.
On the third day, after the morning prayers, the Prophet summoned Ali. Hazrat Ali immediately responded.
He jumped his horse over the moat and with one hand swung open both the gates of the fortress with such force that they broke off their hinges. He carried them and put them across the moat to form a bridge. The Muslims rode into the fortress and conquered Khaiber.
Now let us go back to Kerbala. When Imaam Hussain got to where Akber lay he took him in his arms. Akber had his right hand on the chest. He placed his left arm over the shoulder of his father.
Hussain said "Akber, why do you embrace me with one arm only?" Akber would not reply. Hussain tried to move Akber hand.
Akber resisted. Imaam gently moved the hand. Then he saw it! He saw the blade of the spear. Imaam Hussain laid Ali Akber on the ground and sitting on his knees he put both his hands on the blade of the spear.
He then looked at Najaf, and cried out, "Father, I too have come to my Khaiber!" He pulled out the blade. Jibraeel cried out "Marhaba! Marhaba!" Akber took a deep sigh and then lay still.
