Brief commentary
They said to one another: “Each one of you should swear by Allah that we will go to him and the believers with him at night, then we will kill them and then say to the one responsible for avenging his blood: ‘We were not present at the murder of Salih or the murder of his followers, and we are truthful in what we have said’”.
