Then do they await except that the Hour should come upon them (47:18)

Almuntakhab Fi Tafsir Alquran Alkarim

Do they (The infidel Meccans together with the hypocrites) intend to remain in their state of disbelief until they suddenly face the foreordained Hour? But its shadows have been cast and its preceding signs have come into peoples knowledge; and so where can they turn and what can profit them when it comes upon them

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(47:18) Are they waiting, then, for anything else than the Last Hour to suddenly come upon them? *29 Already some of its tokens have come. *30 But when it does actually come upon them, where will any time be left for them to take heed?

Then do they await except that the Hour should come upon them meaning

*29) That is, as far as the explanation andclarification of the truth is concerned; it has been explained fully well by argument and reasoning, the miraculous discourses of the Qur'an, the pure character of the Prophet Muhammad (upon whom be Allah's peace) and the revolution in the lives of his Companions. Now, are these people awaiting that Resurrection itself should take place and then only they will believe? ,
*30) Theportents of Resurrection imply those signs which indicate that its approach is near. One such important sign is the advent of God's Last Prophet after whom no other prophet will come till Resurrection. Traditions have been related in Bukhari, Muslim. Tirmidhi and Musnad Ahmad on the authority of Hadrat Anas, Hadrat Sahl bin Sa'd As-Sa'idi and Hadrat Buraidah, saying that the Holy Prophet raised his index finger and the middle finger and said: "My advent and Resurrection are like these two fingers." That is, 'Just as there is no other finger between these two fingers, so no other prophet will be raised between the and Resurrection; after me only Resurrection now will occur."

اب کیا یہ لوگ بس قیامت ہی کے منتظر ہیں کہ وہ اچانک اِن پر آ جائے؟ اُس کی علامات تو آ چکی ہیں جب وہ خود آ جائے گی تو اِن کے لیے نصیحت قبول کرنے کا کونسا موقع باقی رہ جائے گا؟
