It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) said to the members of the Shura: "Are you willing for me to choose (the caliph) for you while I myself withdraw from this matter (the nomination for the caliphate)?" At this Sayyiduna Ali (may Allah be pleased with him) said: "Yes, I am the first to agree to this proposal, for I heard the Messenger of Allah (peace and blessings be upon him) say: 'You are trustworthy (amin) among the inhabitants of the heavens, and trustworthy among the inhabitants of the earth.'"
And the hadith: "Indeed I hope to wear it in this world and the Hereafter" has already passed in the Book of Clothing.
