Musnad Ahmed: Hadith 3762

There was a man who had never done any good deed except believing in the Oneness of Allah (Tawheed). When he was dying, he said to his family: When I die take me and burn me until I become like charcoal. Then grind me up and scatter me on the sea on a windy day. So they did that for him, then he immediately found himself in the grasp of Allah. Allah, may He be glorified and exalted, said to him: What made you do what you did? He said: Fear of You. And Allah forgave him.
