Killing a believer due to him being a believer
Q: Is there repentance for murder of a Muslim because there is a verse in the Noble Quran which says:
“And whoever kills a Believer intentionally then their recompense is Hell-Fire, abiding therein forever; and upon them is the anger of Allah and His curse and for them is a painful punishment.” [Quran; 04:93]
Secondly, as I have also heard there is also a report attributed to Ibn Abbas had said that there is no repentance for the intentional killing of a believer.
However on the contrary, large number of Ulama and Muftis say that there is repentance for the intentional murder even of a believer?
