It is narrated from Sayyiduna Abu Jum'ah (may Allah be pleased with him) that once we were partaking in the morning meal with the Prophet (peace and blessings be upon him), and Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) was also with us. He said: O Messenger of Allah! Will there be anyone better than us? We accepted Islam at your hand and fought in jihad in your company. He replied: "Yes, there will be a people who will come after you and will believe in me without having seen me."
