Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that a man brought a bridled she-camel and said: O Messenger of Allah! This she-camel is for jihad in the way of Allah. The Prophet (peace and blessings of Allah be upon him) said: "For you, in exchange for it, there will be seven hundred she-camels in Paradise, all of them bridled."
