Muwatta Imam Malik Book of Burials, Hadith 52

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "A man said to his family that he had never done a good action, and that when he died they were to burn him and then scatter half of him on the land and half of him on the sea, and by Allah, if Allah destined it for him He would punish him with a punishment which He had not punished anyone else with in all the worlds. When the man died, they did as he had told them. Then Allah told the land to collect everything that was in it, and told the sea to collect everything that was in it, and then He said to the man, 'Why did you do this?' and he said, 'From fear of You, Lord, and You know best.' "
Abu Hurayra added, "And He forgave him."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " قَالَ رَجُلٌ لَمْ يَعْمَلْ حَسَنَةً قَطُّ لأَهْلِهِ إِذَا مَاتَ فَحَرِّقُوهُ ثُمَّ اذْرُوا نِصْفَهُ فِي الْبَرِّ وَنِصْفَهُ فِي الْبَحْرِ فَوَاللَّهِ لَئِنْ قَدَرَ اللَّهُ عَلَيْهِ لَيُعَذِّبَنَّهُ عَذَابًا لاَ يُعَذِّبُهُ أَحَدًا مِنَ الْعَالَمِينَ . فَلَمَّا مَاتَ الرَّجُلُ فَعَلُوا مَا أَمَرَهُمْ بِهِ فَأَمَرَ اللَّهُ الْبَرَّ فَجَمَعَ مَا فِيهِ وَأَمَرَ الْبَحْرَ فَجَمَعَ مَا فِيهِ ثُمَّ قَالَ لِمَ فَعَلْتَ هَذَا قَالَ مِنْ خَشْيَتِكَ يَا رَبِّ وَأَنْتَ أَعْلَمُ . قَالَ فَغَفَرَ لَهُ " .
