كَدَأْبِ ءَالِ فِرْعَوْنَ وَٱلَّذِينَ مِن قَبْلِهِمْ ۚ كَذَّبُوا۟ بِـَٔايَٰتِنَا فَأَخَذَهُمُ ٱللَّهُ بِذُنُوبِهِمْ ۗ وَٱللَّهُ شَدِيدُ ٱلْعِقَابِ
Like Pharaoh's folk and those who were before them, they disbelieved Our revelations and so Allah seized them for their sins. And Allah is severe in punishment.

Chapter: Saying "Wailaka."
Narrated Anas:
A bedouin came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! When will The Hour be established?" The Prophet (ﷺ) said, "Wailaka (Woe to you), What have you prepared for it?" The bedouin said, "I have not prepared anything for it, except that I love Allah and H is Apostle." The Prophet (ﷺ) said, "You will be with those whom you love." We (the companions of the Prophet (ﷺ) ) said, "And will we too be so? The Prophet (ﷺ) said, "Yes." So we became very glad on that day. In the meantime, a slave of Al-Mughira passed by, and he was of the same age as I was. The Prophet (ﷺ) said. "If this (slave) should live long, he will not reach the geriatric old age, but the Hour will be established."
