Say;
"He will give life to them Who created them for the first time! And He is the All-Knower of every creation!"
meaning, He knows about the bones in all areas and regions of the earth, where they have gone when they disintegrated and dispersed.
Imam Ahmad recorded that Rib`i said;
""Uqbah bin `Amr said to Hudhayfah, may Allah be pleased with him, `Will you not tell us what you heard from the Messenger of Allah?'
He said, `I heard him say;
إِنَّ رَجُلً حَضَرَهُ الْمَوْتُ فَلَمَّا أَيِسَ مِنَ الْحَيَاةِ أَوْصَى أَهْلَهُ إِذَا أَنَا مُتُّ فَاجْمَعُوا لِي حَطَبًا كَثِيرًا جَزْلاً ثُمَّ أَوْقِدُوا فِيهِ نَارًا حَتْى إِذَا أَكَلَتْ لَحْمِي وَخَلَصَتْ إِلَى عَظْمِي فَامْتُحِشْتُ فَخُذُوهَا فَدُقُّوهَا فَذَرُّوهَا فِي الْيَمِّ فَفَعَلُوا فَجَمَعَهُ اللهُ تَعَالَى إِلَيْهِ ثُمَّ قَالَ لَهُ لِمَ فَعَلْتَ ذَلِكَ قَالَ مِنْ خَشْيَتِكَ فَغَفَرَ اللهُ عَزَّ وَجَلَّ لَه
Death approached a man and when there was no longer any hope for him, he said to his family,
"When I die, gather a lot of firewood, then set it ablaze until my flesh is consumed and it reaches my bones and they become brittle. Then take them and grind them, and scatter them in the sea."
So they did that, but Allah gathered him together and said to him;
"Why did you do that?"
He said, "Because I feared You."
So Allah forgave him.'
Uqbah bin `Amr said, `I heard him say that, and the man was a gravedigger."'
Many versions of this Hadith were recorded in the Two Sahihs.
One of these versions mentions that he commanded his sons to burn him and then grind his remains into small pieces, and then scatter half of them on land and half of them on the sea on a windy day. So they did that, then Allah commanded the sea to gather together whatever remains were in it, and He commanded the land to do likewise, then he said to him, "Be!", and he was a man, standing.
Allah said to him. "What made you do what you did?"
He said, "The fear of You, and You know best."
Straight away He forgave him.
Allah says;
الَّذِي جَعَلَ لَكُم مِّنَ الشَّجَرِ الاَْخْضَرِ نَارًا فَإِذَا أَنتُم مِّنْهُ تُوقِدُونَ
