Is it permissible to curse murderers who kill innocent people?

Dear Brother / Sister,

Allah has never allowed oppression to continue. When we look at the history of humanity, we see that the oppressing people and states were punished severely for what they had done sooner or later.

We definitely hope that this oppression would end soon and the Muslims would get rid of this oppression. 

Besides, the Muslims that die due to oppression die as martyrs. This oppression enables them to gain a happy, eternal life in the hereafter in return for this short, troublesome world life.  

Islamic scholars have different views about what people to curse and damn. Some scholars hold the view that it is not permissible to curse and damn Muslims. Others hold the view that it is permissible to curse sinners even if they are Muslims. They also have different ideas about cursing and damning unbelievers.

Some scholars say it is permissible to curse and damn unbelievers unconditionally while others say it is not wajib to curse them hence it is better not to curse and damn them unconditionally. (Fakhruddin ar-Razi, Tefsi al-Kabir Trnsl. III/188; Ibn Majah, Translation and Expalantion, X/148)
