And when that comes, carry me upon a she-camel until when I head out into the wilderness, a veiled Bedouin will come to you and request from you the trust - meaning that you hand over to him the rein of the she-camel - so hand it over to him."

And when they went out with their father into the breadth of the wilderness, at that moment a veiled Bedouin came to them saying to them: "Peace be upon you, O sons of the guardian (wali) of Allah and His deposit in His earth." So they answered his greeting, and he was saying to them: "Fulfill the trust to me." And al-Abbas was leading the she-camel, and al-Husayn was on its right, and al-Hasan was on its left. So al-Husayn said: "O Abbas, give the rein of the she-camel to its seeker." Al-Abbas answered him: "How can we hand over the purified body of our father to someone we do not know?" And scarcely had al-Abbas finished his sentence when the veil was slowly removed, and the luminous face of Imam Ali appeared there! Al-Abbas said: "What is this astonishing matter? This is the body of our father on the back of the she-camel, and here is our father, we see him before us!"
