From him عليه السلام, from his father عليه السلام, from his forefathers عليه السلام, peace be upon them, who said:
Imam al-Sadiq عليه السلام said that the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, said: “Align your rows evenly and level your shoulders with one another, so that Satan does not gain control over you.” (meaning spiritual control)
