It seems to be a lot of opinions flying around here.
A picture clearly does not invalidate your prayer.
Pictures are makrooh to be where one prays (all the walls, the body, covered or uncovered- it does not matter).
Tattoos are halal. We don't make halal things haram because we don't like them.
who are people trying to impress by getting tatoos...wearing chains...with their pants down below sea level...and bandannas, and earrings....y do dey think ther so kool
Islam is such a beautiful thing where in each person is entitled to his/her own style and culture. If it includes wearing baggy pants, loose pants, so be it. Some people say it came from the style in prison (the clothes were baggy and often the wrong size), but perhaps, it is from African style after all, I know west Africans wear huge baggy shirts and pants. I don't thikn its any issue of impressing. It is what you see people around you wear it and is that particular community's norm. Now, when a white boy (except those that also live in the ghetto) it is usually because he just wants to be like the new HIP-HOP music industry hype and all "ghetto fabulous."
