Malik narrated that Jubayr bin Mut`im said, "I heard the Prophet reciting Surat At-Tur while praying Maghrib. Surely, I have never heard a more beautiful voice or recitation than his recitation." This Hadith is recorded in the Two Sahihs using a chain of narration that includes Malik. Al-Bukhari recorded that Umm Salamah said, "I complained of being ill to the Messenger of Allah ﷺ, and he said,
«طُوفِي مِنْ وَرَاءِ النَّاسِ وَأَنْتِ رَاكِبَة»
(Perform Tawaf (of the Ka`bah) behind the crowd, while you are riding.) So, I performed Tawaf while the Messenger of Allah ﷺ was praying beside the House, reciting At-Tur."
وَالْبَحْرِ الْمَسْجُورِ (and by the sea, filled up with fire...52:6) The word bar means sea and the passive participle masjur is derived from sajr which is used in several different senses, one of which is to kindle with fire. Some of the commentators interpret the participle in this sense here, that is, by the sea which will be kindled with fire on the Day of Resurrection, just as Allah said in another verse وَإِذَا الْبِحَارُ سُجِّرَتْ "And when the seas will be kindled with fire". In other words, it will be kindled with fire and become a raging fire surrounding the people in the plain of hashr. This was reported by Sayyidna Said Ibn Musayyab from Sayyidna Ali Ibn Abi Talib ؓ . Sayyidna Ibn ` Abbas, Mujahid, and ` Ubaidullah Ibn ` Umair ؓ also report likewise. (Ibn Kathir)
A Jewish person asked Sayyidna ` Ali ؓ 'where is the Hell?'. He replied 'the sea'. The Jew, who was the scholar of the previous scriptures, confirmed this. (Qurtubi) Sayyidna Qatadah ؓ and others interpreted the phrase to mean 'filled sea'. Ibn Jarir (رح) preferred this interpretation (Ibn Kathir). ' This is the interpretation adopted by Maulana Ashraf Thanawi (رح)
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 1–15
Mount Tur is that mountain in the desert of Sinai where Moses was awarded prophethood. The Scripture penned on unrolled parchment or the written Book (kitabun mastur) here means the Torah. The frequented house (al-bayt al-ma‘mur) means the Kabah. The lofty vaults of the sky or high roof (as-saqf al-marfu‘) means the sky. The swelling sea (al-bahr al-masjur) means a sea with waves. All these things bear testimony that the Day of seizure by God is certain to come. Almighty God has repeatedly given these very tidings through the prophets. This has also been mentioned in ancient holy scriptures. Heaven and earth announce this in their silent language. The waves of the sea relate this story to every listener.
