Sunan Abi Dawud, Hadith 3863 ⓘ
Abu Hurairah reported the Messenger of Allah as saying: If anyone drinks poison, the poison will be in his hand (on the Day of Judgement) and he will drink it in Hell-fire and he will live in it eternally.
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ حَسَا سُمًّا فَسُمُّهُ فِي يَدِهِ يَتَحَسَّاهُ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا " .
