You attacked a dead man for the color of his beard. This is not right. A true Muslim or defender of Islam would merely say that you neither can judge or criticize what he has done. Our words are very powerful and there are many things to talk about today such as the floods or the situation in Cairo. I suggest you let the dead rest and let Allah judge him on his color or not.
You might read one of my many articles on Islam before you start quoting unauthentic hadiths. Or should I say weak hadiths.
