Why are pictures haram?

Picture frames and photographs of animate objects are not permissible to
display. Frames having pictures of inanimate objects e.g. trees, mountains,
etc. are permissible.
- Hadhrat Abu Talha (Radhiyallaahu Ánhu) narrates that Nabi (Sallallaahu
Álayhi Wasallam) said, 'Angels do not enter a house wherein there is a dog
or picture.' (Mishkãt vol. 2 p. 385)
? Ábdullah ibn Masóod (Radhiyallaahu Ánhu) narrates that Rasulullah
(Sallallaahu Álayhi Wasallam) said, 'The people with the most severe
punishment by Allah will be the picture makers.' (Ibid).
? Hadhrat Ibn Abbas (RA) narrates, 'I heard the messenger of Allah saying,
"Every picture-maker will be in the fire. A life will be created for every
picture the picture-maker made, and he will be tortured in Hell."
If you have to make pictures (says Ibn Abbaas) then make a picture of a tree
or such things which are inanimate.' (Bukhari and Muslim)
