Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Tufail (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) smiled, and smiled greatly, then said: "Will you ask me about the reason for my smile?" We said: O Messenger of Allah! Why did you laugh? He (peace and blessings be upon him) said: "I saw some people from my Ummah being taken towards Paradise in chains, and Paradise was extremely disliked by them!" We said: Who are those people? He (peace and blessings be upon him) said: "They are non-Arabs, whom the Muhajirun captured and brought into Islam as prisoners."
