Al-Husayn ibn Muhammad and Muhammad ibn Yahya have all narrated from Ali ibn Muhammad ibn Sa’d from Muhammad ibn Aslam from Muhammad ibn Ali ibn ‘Uday who has said that dictated to h him Muhammad ibn Sulayman from Ishaq ibn ‘ Ammar who has said the following: “Abu ‘Abd Allah  has said, ‘Be good to my friends, O Ishaq, as much as you can. No believer does something good to another believer or assists him, but that it causes a contusion to the face of Satan and injuries to his heart.’”
