How can you disbelieve in Allāh when you were lifeless and He brought you to life; then He will cause you to die, then He will bring you [back] to life, and then to Him you will be returned. (Surah Al-Baqarah, 2:28)

أَوْ كَالَّذِي مَرَّ عَلَىٰ قَرْيَةٍ وَهِيَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا قَالَ أَنَّىٰ يُحْيِي هَٰذِهِ اللَّهُ بَعْدَ مَوْتِهَا فَأَمَاتَهُ اللَّهُ مِائَةَ عَامٍ ثُمَّ بَعَثَهُ قَالَ كَمْ لَبِثْتَ قَالَ لَبِثْتُ يَوْمًا أَوْ بَعْضَ يَوْمٍ قَالَ بَل لَّبِثْتَ مِائَةَ عَامٍ فَانظُرْ إِلَىٰ طَعَامِكَ وَشَرَابِكَ لَمْ يَتَسَنَّهْ وَانظُرْ إِلَىٰ حِمَارِكَ وَلِنَجْعَلَكَ آيَةً لِّلنَّاسِ وَانظُرْ إِلَى الْعِظَامِ كَيْفَ نُنشِزُهَا ثُمَّ نَكْسُوهَا لَحْمًا فَلَمَّا تَبَيَّنَ لَهُ قَالَ أَعْلَمُ أَنَّ اللَّهَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ ٢٥٩

كَيْفَ kayfa · how

Or [consider such an example] as the one who passed by a township which had fallen into ruin. He said, "How will Allāh bring this to life after its death?" So Allāh caused him to die for a hundred years; then He revived him. He said, "How long have you remained?" He [the man] said, "I have remained a day or part of a day." He said, "Rather, you have remained one hundred years. Look at your food and your drink; it has not changed with time. And look at your donkey; and We will make you a sign for the people. And look at the bones [of this donkey] - how We raise them and then We cover them with flesh." And when it became clear to him, he said, "I know that Allāh is over all things competent." (Surah Al-Baqarah, 2:259)
