Ubadah bin al-Samit (may Allah be pleased with him) said: I was one of the leaders (nuqaba') who gave the pledge of allegiance to him (peace and blessings be upon him), (pledging) that "we would not associate anything with Allah, nor commit adultery, nor steal, nor kill a soul that Allah has made sacred except by right, nor plunder, nor disobey; if we did that, Paradise would be ours; and if we committed any of these things, our judgement rests with Allah, the Mighty and Majestic."
