from the Prophet ﷺ, regarding this Ayah "Say: He has the power to send torment on you from above or from under your feet...' the Prophet ﷺ said "Indeed they shall be, even though they have not occurred as of yet." (Using translation from Tirmidhī 3066)
سُئِلَ رَسُولُ اللهِ ﷺ عَنْ هَذِهِ الْآيَةِ {هُوَ الْقَادِرُ عَلَى أَنْ يَبْعَثَ عَلَيْكُمْ عَذَابًا مِنْ فَوْقِكُمْ أَوْ مِنْ تَحْتِ أَرْجُلِكُمْ} [الأنعام 65] فَقَالَ رَسُولُ اللهِ ﷺ أَمَا إِنَّهَا كَائِنَةٌ وَلَمْ يَأْتِ تَأْوِيلُهَا بَعْدُ
