13. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn al-Hakam from Sayf ibn ‘Amirah from ‘Abd Allah ibn Muskan from Ibrahim ibn Shu’ayb who has said the following: “Once I said to Abu ‘Abdillah ‘My father has become very old and weak. We pick him up and help him for the restrooms.’ The Imam said, ‘If you can, you should do all of this for him and feed him with your own hand; it is paradise for you tomorrow. ’”
