Abu'd-Darda' said, "Shall I tell you about something better for
you than sadaqa and fasting? Improving the state of friendship. Hatred
is what shaves things away."
Abu Hurayra reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "The gates of the Garden are opened on Mondays
and Thursdays. Every person who does not associate anything with Allah
is forgiven except for someone who has enmity between existing between
him and another man. It is said, 'Leave these two until they make peace.'"
Narrated Ibn 'Abbas reported that the Prophet, may Allah bless him and grant
him peace, said, "Three things are not concealed and He forgives everything
else to whomever He wills:
the one who dies and has not associated anything
with Allah, the one who was not a sorcerer nor a follower of the sorcerers,
and the one who did not have rancour towards his brother."
Abu Hurayra reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "Beware of opinion. Opinion is the most
lying form of speech. Do not try to ensnare one another (in sales) nor
envy one another nor hate one another nor shun one another. Rather be the
slaves of Allah and brothers."
