Ibn Abbas that he says, I was along with the Commander of the faithful Imam Ali (a.s.) when we were going towards Siffīn. When we passed by Naynawah, on the banks of the River Euphrates (Furat), Imam Ali said in a loud voice,
“O Ibn Abbas! Do you recognize this place”?
I replied in the negative. Imam continued,
“If you had known that what I know, you would not move from here without weeping.”
Then Imam Ali (a.s.) wept such bitterly that his beard became wet and tears started falling on his chest, and I too started weeping. He started calling out,
“Alas! What business the children of Abu Sufyan and Harb have with me, they being of the group of shaitan and friends of disbelief. O Aba Abdillah (Imam Husayn)! Adhere to patience and forbearance. Your father sees all that which shall befall you.”
Then he called for water and performed ablutions and recited Prayers as much as he desired and then repeated what he said before. After finishing he slept for sometime and then awoke and called me. I said, “Here I am at your service, O Commander of the faithful.” Imam Ali (a.s.) said,
“Shouldn’t I narrate to you what I dreamt now”?
I replied, “Verily you slept and what you dreamt would be true and fair, O Commander of the faithful.” Imam replied,
“I dreamt that some men have descended from the heavens carrying white standards and equipped with bright and shining swords and have drawn a line on this ground. I saw that the branches of the palm-trees are reaching on the ground and frantic pure blood was dripping from them. And I saw my dear son and the light of my eyes Husayn smeared in blood calling out for help, but nobody is responding to them.
The men who had descended from the heavens are calling to him: O Progeny of Prophet! Adhere to patience and forbearance, for you will be killed at the hands of the most accursed people. O Aba Abdillah (Imam Husayn)! This is Paradise that eagerly awaits you.
Then they condoled me and said: O Abul Hasan! Glad tidings to you, for on the day of Qiyamah, Allah will cool your eyes due to him, then I awoke as you now see. By Him in whose hands is Ali’s life! The most honest Abul Qasim (Holy Prophet) had related to me, that I would come to this valley, whilst going to fight the rebellions and mischievous people. And this valley is known as Karbobala, where my Husayn together with seventeen people among mine and Fatima’s progeny would be buried, and this place is renowned in the heavens. And this place of Karb (grief) and Bala (trials) will be mentioned as the two Harams (of Ka’bah and Prophet’s Mosque) and Baitul Muqaddas are mentioned.”
