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: Avoid the seven sins that destroy faith. The Companions asked: O Messenger of Allah! What are those sins? He (peace be upon him) said: 1. Associating partners with Allah. 2. Practicing magic. 3. Killing a soul whom Allah has forbidden to kill, except with due right. 4. Consuming usury. 5. Consuming the property of an orphan. 6. Fleeing from the battlefield on the day of fighting. 7. Slandering chaste, believing, innocent women who are unaware of indecency.
