Allah's Apostle sent out ten spies under the command of `Asim bin Thabit Al-Ansari, the grand-father of `Asim bin `Umar Al-Khattab. When they reached (a place called) Al-Hadah between 'Usfan and Mecca, their presence was made known to a sub-tribe of Hudhail called Banu Lihyan. So they sent about one hundred archers after them. The archers traced the footsteps (of the Muslims) till they found the traces of dates which they had eaten at one of their camping places. The archers said, "These dates are of Yathrib (i.e. Medina)," and went on tracing the Muslims' footsteps. When `Asim and his companions became aware of them, they took refuge in a (high) place. But the enemy encircled them and said, "Come down and surrender. We give you a solemn promise and covenant that we will not kill anyone of you." `Asim bin Thabit said, "O people! As for myself, I will never get down to be under the protection of an infidel. O Allah! Inform your Prophet about us." So the archers threw their arrows at them and martyred `Asim. Three of them came down and surrendered to them, accepting their promise and covenant and they were Khubaib, Zaid bin Ad-Dathina and another man. When the archers got hold of them, they untied the strings of the arrow bows and tied their captives with them. The third man said, "This is the first proof of treachery! By Allah, I will not go with you for I follow the example of these." He meant the martyred companions. The archers dragged him and struggled with him (till they martyred him). Then Khubaib and Zaid bin Ad-Dathina were taken away by them and later on they sold them as slaves in Mecca after the event of the Badr battle. The sons of Al-Harit bin `Amr bin Naufal bought Khubaib for he was a person who had killed (their father) Al-Hari bin `Amr on the day (of the battle) of Badr. Khubaib remained imprisoned by them till they decided unanimously to kill him. One day Khubaib borrowed from a daughter of Al-Harith, a razor for shaving his pubic hair, and she lent it to him. By chance, while she was inattentive, a little son of hers went to him (i.e. Khubaib) and she saw that Khubaib had seated him on his thigh while the razor was in his hand. She was so much terrified that Khubaib noticed her fear and said, "Are you afraid that I will kill him? Never would I do such a thing." Later on (while narrating the story) she said, "By Allah, I had never seen a better captive than Khubaib. By Allah, one day I saw ...
