Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Hawalah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said one day: "Suddenly, you will rush upon a man (to pledge allegiance to him) who will be wrapped in a striped cloak; he will take allegiance from the people, and he will be among the people of Paradise." (One day it happened that) we rushed upon Sayyiduna Uthman bin Affan (may Allah be pleased with him) to pledge allegiance to him, and he was wrapped in a striped cloak.
