The Messenger of Allah ﷺ said, "Whoever believes in Allah and His Messenger, establishes the prayer, and fasts Ramadan, it is a right upon Allah to admit him into Paradise, whether he struggles in the path of Allah or remains in the land where he was born."They said, "Messenger of Allah, shall we not give the people this glad tidings?"He replied, "In Paradise there are one hundred ranks that Allah has prepared for those who strive in His path. Between each two ranks is the distance between the heavens and the earth. So when you ask Allah, ask Him for Firdaws, for it is the middle of Paradise and the highest part of Paradise. Above it, I believe, is the Throne of the Most Merciful, and from it the rivers of Paradise gush forth."
قال رسول الله ﷺ: من آمن بالله ورسوله، وأقام الصلاة، وصام رمضان، كان حقا على الله أن يدخله الجنة، جاهد في سبيل الله، أو جلس في أرضه التي ولد فيها: فقالوا: يا رسول الله أفلا نبشر الناس؟ قال: إن في الجنة مائة درجة السماء أعدها الله للمجاهدين في سبيل الله، ما بين الدرجتين كما بين والأرض، فإذا سألتم الله فاسألوه الفردوس، فإنه أوسط الجنة، وأعلى الجنة- أراه فوقه- عرش الرحمن، ومنه تفجر أنهار الجنة.
Bukhari narrated it in the Book of Jihad and Expeditions (2790) from Yahya bin Salih, who said, Fulayh narrated to us, from Hilal bin Ali, from Ata bin Yasar, from Abu Hurairah, and he mentioned it.
