Jabir told that God's messenger looked at Talha b. `Ubaidallah and said, "If anyone wants to look at a man walking on the face of the earth when he has died[*] let him look at this man." A version has, "If anyone finds pleasure in looking at a martyr walking on the face of the earth let him look at Talha b. `Ubaidallah."
*The idea may be that he has vowed to fight to death in God's path, and so he is spoken of as being as good as dead.
Tirmidhi transmitted it.
