Allah said;

ثُمَّ إِذَا شَاء أَنشَرَهُ ﴿٢٢﴾

Then when it is His will, He will resurrect him.

meaning, He resurrects him after his death and this is called Al-Ba`th (resurrection) and An-Nushur (resuscitation).

وَمِنْ ءَايَـتِهِ أَنْ خَلَقَكُمْ مِّن تُرَابٍ ثُمَّ إِذَآ أَنتُمْ بَشَرٌ تَنتَشِرُونَ

And among His signs is this that He created you from dust, and then behold, you are human beings scattered. (30:20)

وَانظُرْ إِلَى العِظَامِ كَيْفَ نُنشِزُهَا ثُمَّ نَكْسُوهَا لَحْمًا

And look at the bones, how We bring them together and clothe them with flesh. (2:259)

In the Two Sahihs it is narrated by way of Al-A`mash from Abu Salih, from Abu Hurayrah that the Prophet said,

كُلُّ ابْنِ آدَمَ يَبْلَى إِلَّا عَجْبَ الذَّنَبِ، مِنْهُ خُلِقَ، وَفِيهِ يُرَكَّب

All of the Sons of Adam (men) will decay except for the bone of coccyx (tailbone). From it he (man) was created and by it he will be reconstructed.''
