The Prophet 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 migrated in the cause of Allah or remained in the land in which he was born."They asked, "Messenger of Allah, shall we not inform the people of this?"He replied, "In Paradise there are a hundred ranks that Allah has prepared for those who strive in His cause. Between every two ranks is a distance like that 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 is the Throne of the Most Merciful, and from it the rivers of Paradise burst forth."
عن النبي ﷺ قال: من آمن بالله ورسوله، وأقام الصلاة، وصام رمضان، كان حقا على الله أن يدخله الجنة، هاجر في سبيل الله، أو جلس في أرضه التي ولد فيها، قالوا: يا رسول الله، أفلا ننبئ الناس بذلك؟ قال: إن في الجنة مائة درجة، أعدها الله للمجاهدين في سبيله، كل درجتين ما بينهما كما بين السماء والأرض، فإذا سألتم الله فسلوه الفردوس، فإنه أوسط الجنة، وأعلى الجنة، وفوقه عرش الرحمن، ومنه تفجر أنهار الجنة.
