Asslam Alaikam DR Zakir Naik.
Sir Iam from Pakistan and my question is that in shia book named Al kafi it narrated by Hazrat Imam Jaffar R.A that black clothes are the culture of Hellfires and it is also culture of Pharaoh so if I want to put black paint shirt or fullsuite than it is also Haram? Please explain something.
Jazakallah Khairan.

ISIS doesn't mind wearing black clothes. They allege to be Muslim.

Usually wearing black clothes make men sad overtime and this is haram because you are hurting yourself (mentally).. that's why he said it's harram.. but my favorite colour is Black and I have black shirt and other stuff.. it's depend on you my friend wear it but don't be sad... it's not harram enjoy black colour :D
