Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“In Paradise, there is a special gate for those who fast, which is called Rayyan. No one except those who fast will enter through it. When the last of those who fast has entered, that gate will be closed. Whoever enters Paradise will drink the heavenly drink, and whoever drinks it will never feel thirsty again.”Abu Hazim Salamah bin Dinar is a trustworthy narrator; in his time, there was no scholar like him.
