It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that a man asked the Messenger of Allah (peace and blessings be upon him): O Messenger of Allah! Glad tidings (Tuba) are for those people who saw you and believed in you. The Messenger of Allah (peace and blessings be upon him) said: Yes, indeed, glad tidings are for those who saw me and believed in me, but glad tidings, glad tidings, glad tidings are for those who believed in me without seeing me. That man asked: What is Tuba? The Messenger of Allah (peace and blessings be upon him) said: It is the name of a tree in Paradise, and it is as vast as a hundred years’ journey. The garments of the people of Paradise are made from the sheaths of its buds.
