Mukhtasar Muslim

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: Beware of suspicion, for suspicion is the greatest falsehood. Do not listen to others’ conversations, do not spy, do not envy one another (except in matters of religion, which is permissible), do not be jealous, do not harbor malice, do not cut off relations, and be, O servants of Allah, brothers to one another.
