049.010 The Believers are but a single Brotherhood: So make peace and
reconciliation between your two (contending) brothers; and fear Allah,
that ye may receive Mercy.
049.011 O ye who believe! Let not some men among you laugh at others:
It may be that the (latter) are better than the (former): Nor let some
women laugh at others: It may be that the (latter are better than the
(former): Nor defame nor be sarcastic to each other, nor call each
other by (offensive) nicknames: Ill-seeming is a name connoting
wickedness, (to be used of one) after he has believed: And those who do
not desist are (indeed) doing wrong.
049.012 O ye who believe! Avoid suspicion as much (as possible): for
suspicion in some cases is a sin: And spy not on each other behind
their backs. Would any of you like to eat the flesh of his dead
brother? Nay, ye would abhor it...But fear Allah: For Allah is
Oft-Returning, Most Merciful.
