5. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from his father from Muhammad ibn Sinan from Mufaddal ibn ‘Umar who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘A believer must not humiliate himself.’ I then asked, ‘In what way can he humiliate himself?’ He (the Imam) replied, ‘He can do so by involving himself in things that he cannot do.’”

6. Muhammad ibn Ahmad has narrated from ‘Abd Allah ibn al-Salt from Yunus from Sama‘ah who has said the following: “Abu ‘Abd Allah (a.s.), has said that Allah, the most Majestic, the most Glorious, has delegated all affairs of believers to them but He has not delegated him to humiliate himself. Has he not seen the words of Allah, the most Majestic, the most Glorious: ‘All honor belongs to Allah, His Messenger and the believers. . . .’ (63:7) Believers must stand honorable but not humiliated.’”
