Sahl b. Sa'd (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying:In Paradise there is a gate which is called Rayyan through which only the people who fast would enter on the Day on Resurrection. None else would enter along with them. It would be proclaimed: Where are the people who fast that they should be admitted into it? And when the last of them would enter, it would be closed and no one would enter it
