4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hassan ibn Mahbub from Dawud al-Riqqiy who has said the following: “I heard abu ‘Abd Allah عليه السلام, saying, ‘Believers must not humiliate themselves.’ It was asked, ‘How can one humiliate himself?’ He (the Imam) replied, ‘This happens when he does things that are not bearable.’”
