The Day will come when God resurrects them all. They will swear to Him then, just as they swear to you now, thinking that they really are right! Indeed, they are the real liars.
يَومَ يَبعَثُهُمُ اللَّهُ جَميعًا فَيَحلِفونَ لَهُ كَما يَحلِفونَ لَكُم وَيَحسَبونَ أَنَّهُم عَلىٰ شَىءٍ أَلا إِنَّهُم هُمُ الكٰذِبونَ
yawma yab’asuhumul laahujamee’an fa yahlifoona lahoo kamaa yahlifoona lakum wa yahsaboona annahum ‘alaa shai’; alaaa innahum humul kaaziboon
