The Messenger of Allah ﷺ said, "A man who never did any good deed entered Paradise. When death came to him, he said to his family, 'When I die, burn me, then grind me to dust, then scatter half of me into the sea and half onto the land.' So Allah commanded the land and the sea, and they gathered him together. Then He asked, 'What made you do what you did?' He replied, 'Fear of You.' So Allah forgave him for that."
حدثنا معاوية بن هشام حدثنا شيبان أبو معاوية حدثنا فراس بن يحيى الهمداني عن عطية العوفي
أن رسول الله ﷺ قال لقد دخل رجل الجنة ما عمل خيرا قط قال لأهله حين حضره الموت إذا أنا مت فأحرقوني ثم اسحقوني ثم اذروا نصفي في البحر ونصفي في البر فأمر الله البر والبحر فجمعاه ثم قال ما حملك على ما فعلت قال مخافتك قال فغفر له لذلك
Its isnad is hasan, because of Awfi. Shayban is Ibn Abdul-Rahman the grammarian, trustworthy, mentioned previously, and Firas is truthful, and the hadith has been mentioned many times before.
