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'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 he heard the Prophet, may Allah bless
him and grant him peace, say, "It is not lawful for a Muslim man to refuse
to speak to a believer for more than three days. When three days have passed,
he should meet him and greet him. If he returns the greeting, they share
in the reward. If he does not return the greeting, the one who gives the
greeting is innocent of having severed relations."
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.'"
