It is narrated from Sayyiduna Jundub al-Khayr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The prescribed punishment (hadd) of the sorcerer is a single strike with the sword (execution)." This hadith has a sahih (authentic) chain of narration. Although the two Shaykhs (Bukhari and Muslim) left aside the hadith of Isma'il bin Muslim, this is a rare (gharib) and sahih narration. And there is a sahih supporting narration (shahid) on the condition of the two Shaykhs to the contrary of this (that is, concerning the effect of sorcery).
