By Dr. Saleh as-Saleh [d.1429H]
1. Tabarruj is disobedience to Allaah and His Messenger [sall-Allaahu ‘alayhi wa sallam]
The one who disobeys Allaah and His Messenger [sall-Allaahu ‘alayhi wa sallam] can only harm himself and can not in any way harm Allaah: The Messenger [sall-Allaahu ‘alayhi wa sallam] said:
“All of my followers will enter Paradise except those who refuse.” It was asked: “O Messenger of Allaah, who would refuse?” He [sall-Allaahu ‘alayhi wa sallam] said: “He who obeys me enters Paradise and he who disobeys me has refused.” [Reported by al-Bukhaaree]
It is reported that Mu’awiyyah [radee Allaahu ‘anhu] gave a sermon in Greater Syria and in it he mentioned that the Prophet [sall-Allaahu ‘alayhi wa sallam] prohibited seven things and he named tabarruj as one of them.
