“Abdur-Rahman bin Abi Laila told me to ask Ibn ‘Abbas about two Verses: ‘And whoever kills a believer intentionally, his recompense is Hell.’ I asked him and he said: ‘Nothing of this has been abrogated.’ (And I asked him about the Verse): ‘And those who invoke not any other ilah (god) along with Allah, or kill such person as Allah has forbidden, except by right,’ he said: ‘This was revealed concerning the people of Shirk.'”
The Messenger of Allah (ﷺ) as saying: Refrain from seven (characteristics) which cause destruction. He was asked: What are they, Messenger of Allah ? He replied: To assign partner to Allah, magic, to kill a soul (man) which is prohibited by Allah except for which is due, to take usury, to consume the property of an orphan, to retreat on the day of the battle, and to slander chaste women, indiscreet but believing. Abu Dawud said: The name Abu al-Ghaith is Salim client of Ibn Muti’.
