The Prophet 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 said, 'Where are those who fasted?' and they will enter through it. When the last of them has entered, it will be shut, and no one else will enter through it."
عن النبي ﷺ قال: إن في الجنة بابا يقال له: الريان. يدخل منه الصائمون يوم القيامة، لا يدخل معهم أحد غيرهم، يقال: أين الصائمون؟ فيدخلون منه، فإذا دخل آخرهم أغلق، فلم يدخل منه أحد.
Bukhari narrated it in the Book of Fasting (1896), and Muslim narrated it in the Book of Fasting (1152), both of them through Khalid bin Mukhlad Qatawani, who said, Sulayman bin Bilal narrated to us, who said, Abu Hazim narrated to me, from Sahl bin Saad, and he mentioned it.
