[39].Surah Al-Zumar [The Groups]: Ayat 20

২০. কিন্তু যারা তাদের পালনকর্তাকে ভয় করে, তাদের জন্যে নির্মিত রয়েছে প্রাসাদের উপর প্রাসাদ। এগুলোর তলদেশে নদী প্রবাহিত। আল্লাহ প্রতিশ্রুতি দিয়েছেন। আল্লাহ প্রতিশ্রুতির খেলাফ করেন না।

Ayat 20. But those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms; one above another under which rivers flow (i.e. Paradise). (This is) the Promise of Allah: and Allah does not fail in (His) Promise.

Tafseer of Surah Al Zumar Ayat 20. But it is for those who fear their Lord. That lofty mansions, one above another, have been built: beneath them flow rivers (of delight): (such is) the Promise of Allah. Never doubt Allah fail in (His) promise. Cf. 29:58, and 34:37. The idea of heaven here is that of a Home of sublimity and beauty, with a picturesque outlook, such as we would describe in this life by the type of a palace by gently-flowing streams. The mansions will also suggest generous space and architectural beauty, tiers upon tiers piled one upon another. Mi 'ad: the time, place and manner of the fulfilment of a Promise. Allah's promise will be fulfilled in all particulars better than we can possibly imagine.

Hazrat Abu Musa (May Allah be pleased with him) said: The Messenger of Allah [SAWW](PBUH) said, "In Jannah the believer will have a tent made of a single hollowed pearl of which the length will be sixty miles in the sky. The believer will have his wives with him and he will visit them and they will not be able to see one another.'' [Al-Bukhari Book 04, Chapter 54, Hadith # 466].

Lesson: as mentioned above in Surah Al-Zumar Ayat 20 “those who fear Allah and keep their duty to their Lord (Allah), for them are built lofty rooms;" This Hadith highlights the merits of pious and Allah's gift to them a tent made of a single hollowed pearl, these bounties will be other than there huge palaces in Paradise that also shows expansiveness and vastness of the Paradise.
