عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنِ الدَّوَاءِ الْخَبِيثِ يَعْنِي السُّمَّ
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) forbade treatment with a foul medicine; by this, he (peace and blessings be upon him) meant poison.
