The Shaykh : ...It has been mentioned to us previously that the Messenger of Allah (peace and blessings be upon him and his family) went out to inform [the people] of the Night of Decree, but two [men] quarreled, so it was taken away. "Quarreled" means to dispute or contend. This is evidence that disputing can be a cause for the removal of good, and it is indeed so. And Allah the Exalted said: [Al-Anfal 8:46].

and do not dispute and [thus] lose courage and [then] your strength would depart
