Sahih al-Bukhari 6480
Narrated Hudhaifa:
The Prophet (ﷺ) said, "There was a man amongst the people who had suspicion as to the righteousness of 
his deeds. Therefore he said to his family, 'If I die, take me and burn my corpse and throw my ashes 
into the sea on a hot (or windy) day.' They did so, but Allah, collected his particles and asked (him), 
What made you do what you did?' He replied, 'The only thing that made me do it, was that I was 
afraid of You.' So Allah forgave him."
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ رِبْعِيٍّ، عَنْ حُذَيْفَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ كَانَ رَجُلٌ مِمَّنْ كَانَ قَبْلَكُمْ يُسِيءُ الظَّنَّ بِعَمَلِهِ، فَقَالَ لأَهْلِهِ إِذَا أَنَا مُتُّ فَخُذُونِي فَذَرُّونِي، فِي الْبَحْرِ فِي يَوْمٍ صَائِفٍ، فَفَعَلُوا بِهِ، فَجَمَعَهُ اللَّهُ ثُمَّ قَالَ مَا حَمَلَكَ عَلَى الَّذِي صَنَعْتَ قَالَ مَا حَمَلَنِي إِلاَّ مَخَافَتُكَ‏.‏ فَغَفَرَ لَهُ ‏"‏‏.‏
