It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: For every group of people who perform a particular deed, there will be a specific door in Paradise through which they will be called to enter. For those who fast, there will be a special door named Rayyan, through which they will be called. Sayyiduna Abu Bakr, may Allah be pleased with him, said: O Messenger of Allah! Will there be anyone who will be invited to enter through all the doors of Paradise? The Prophet, peace and blessings be upon him, said: Yes, and O Abu Bakr! I hope that you will be among those people.
