´It was narrated from Bara' bin Azib that the Messenger of Allah (ﷺ) said:` “If this world were to be destroyed, that would be less significant before Allah (SWT) than the unlawful killing of a believer.”
Benefits and Issues: (1) The status of a believer is very high in the sight of Allah.
(2) Generally, the cause of murder is some worldly benefit; to kill for such a small benefit is a grave mistake because, in the sight of Allah, the life of a believer is more precious than all the treasures of the world.
