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, and he will be engaged in buying and selling with the people, and in that state, he will be of the people of Paradise." (One day it happened that) we crowded around Sayyiduna Uthman bin Affan (may Allah be pleased with him) to pledge allegiance to him, and he was wrapped in a striped cloak and was engaged in buying and selling with the people. In this hadith, «يبايع» refers to buying and selling.
