The Messenger of Allah ﷺ said, "In Paradise there is a gate called ar-Rayyan. Through it those who fasted will enter on the Day of Resurrection, and no one besides them will enter through it. It will be announced, 'Where are those who fasted?' So they will rise, and no one besides them will enter through it. Once they have entered, it will be closed, and no one else will pass through it."In another narration, "Whoever enters it will drink, and whoever drinks will never thirst again."
قال رسول الله ﷺ: إن في الجنة بابا يقال له: الريان يدخل منه الصائمون يوم القيامة لا يدخل منه أحد غيرهم، يقال: أين الصائمون؟ فيقومون، لا يدخل منه أحد غيرهم، فإذا دخلوا أغلق، فلم يدخل منه أحد. وفي رواية: من دخل فيه شرب، ومن شرب لم يظمأ أبدا.
Bukhari related it in the Book of Fasting (1896), and Muslim in the Book of Fasting (1152), through the route of Khalid bin Mukhlad Qatawani, who said, Sulayman bin Bilal narrated to us, who said, Abu Hazim (that is, Salama bin Dinar) narrated to me, from Sahl, and he mentioned it. The wording given is Bukhari's, and Muslim's wording is close to it.As for the second narration, Nasai related it (2236), and Ibn Khuzayma (1902), both from the hadith of Saeed bin Abdul-Rahman, from Abu Hazim, from Sahl. Tirmidhi related it (765) from the hadith of Hisham bin Saad, from Abu Hazim, from Sahl bin Saad. He said, "hasan sahih gharib."
