What did the Prophet Muhammad (saw) purchase from Jabir bin `Abdullah (peace be upon him) when they encountered one another during a Ghazawat?
 Narrated Jabir bin `Abdullah:                     While I was in the company of the Prophet in one of his Ghazawat, he asked, "What is wrong with your camel? Will you sell it?" I replied in the affirmative and sold it to him. When he reached Medina, I took the camel to him in the morning and he paid me its price.
