Portraying animateness is Forbidden
88) Narrated Abu Huraira : I heard the Prophet saying: Allah said: Who will be more transgressor than the one who tries to create the like of My creatures. Let him create an atom or let him create a grain or a barley seed.
(This Hadfth is sound and reported by Bukhari andMuslim).
Scholars since old times have judged drawing and painting animate creatures unacceptable in Islam as per this Hadith, however, they have exempted photography of people for necessary purposes such as passports and I.Ds. As for photography or portraits for memory these are not allowed.
