Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) promised us the expedition to Hind. If I live to see it, I will spend my wealth and my life in it; if I am martyred, I will be among the best of the martyrs, and if I return, I will be Abu Hurayrah the freed one.
Musaddad said: I heard Ibn Dawud say: Abu Ishaq al-Fazari said: "I wish I had taken part in it in exchange for every campaign I have fought in the land of the Romans."
