and followers of Maliki and Hanafi fiqh believe evidence for stoning being the proper Islamic punishment comes not from an alleged Quranic verse but from reports of Muhammad calling for execution of adulterers by stoning found in collections of sound ("sahih") hadith — meaning that the hadith on stoning abrogate the flogging verse in the Quran. Ahmad Hasan agrees that the punishment of "rajm" is based on the Sunnah of the prophet and argues that the wording of the Verse of Rajm found in hadith "appears to be manifestly of a different style than that of the Quranic verses". He also believes that 'Umar's explanation for not including it in the "mus'haf" does not make sense.
