Read and reflect on verse 5122 from Surah Al-Mujaadila: On the Day when God will raise them all from the dead, they will swear before Him as they [now] swear before you, thinking that they are on firm groun...
يَوْمَ يَبْعَثُهُمُ اللَّهُ جَمِيعًا فَيَحْلِفُونَ لَهُ كَمَا يَحْلِفُونَ لَكُمْ ۖ وَيَحْسَبُونَ أَنَّهُمْ عَلَىٰ شَيْءٍ ۚ أَلَا إِنَّهُمْ هُمُ الْكَاذِبُونَ
On the Day when God will raise them all from the dead, they will swear before Him as they [now] swear before you, thinking that they are on firm ground [in their assumptions]. Oh, verily, it is they, they who are the [greatest] liars!
