Imam Husain's (A.S.) Words with Ali Akbar (A.S.)

Uqbah bin Sam'an says, that we went along with the Imam Husain (A.S.) on the way to Kufa and he took a short nap on the horse's back. Then he woke up and uttered the words:
"Verily we are from Allah's and verily unto Him shall we return. Praise be to Allah, the Lord of the worlds."
Then he repeated it twice or thrice. His son Ali bin Husain (Ali Akbar) (A.S.), who was riding a horse, came up to him and asked, "Why did you (suddenly) praise Allah and utter the words of "returning to Him"? Imam (A.S.) replied,
"O my dear son! Sleep overtook me, and I saw a rider come up to me from behind and said: These people are proceeding further, while death is advancing towards them. I perceived that they were our spirits informing us of our death."
Ali bin Husain (A.S.) said, "O dear father! Are we not on the right"? Imam Husain (A.S.) replied,
"Why not, by Him towards Whom all servants return."
Then Ali Akbar (A.S.) said, "Then we do not fear, for we shall die on the right." Imam (A.S.) said,
"May Allah reward you abundantly, the reward which is due from a father to his son."
