يَوْمَ تُقَلَّبُ وُجُوهُهُمْ فِى ٱلنَّارِ يَقُولُونَ يَٰلَيْتَنَآ أَطَعْنَا ٱللَّهَ وَأَطَعْنَا ٱلرَّسُولَا۠
On the day when their faces are turned over in the Fire, they say: Oh, would that we had obeyed Allah and had obeyed His messenger!
Surah Al-Ahzaab(33:66)
Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: The Statement of Allah Most High: "Allah has made the Ka’bah—the Sacred House—a sanctuary of well-being for all people, along with the sacred months, the sacrificial animals, and the ˹offerings decorated with˺ garlands. All this so you may know that Allah knows whatever is in the heavens and whatever is on the earth, and that He has ˹perfect˺ knowledge of everything."
Narrated Abu Sa`id Al-Khudri:
The Prophet (ﷺ) said "The people will continue performing the Hajj and `Umra to the Ka`ba even after the appearance of Gog and Magog." Narrated Shu`ba extra: The Hour (Day of Judgment) will not be established till the Hajj (to the Ka`ba) is abandoned.
