14. Sahl has narrated from Ahmad ibn Muhammad from Muhammad ibn Sama‘ah from ‘Umar ibn Yazid from Muhammad ibn Muslim who has said the following: “Once, a man in al-Kufah came to ’Amir al-Mu’minin , and said, ‘I have divorced my wife after she became clean from her Hayd (menses) and before I went to bed with her.’ ’Amir al- Mu’minin asked, ‘Did you ask two just men to witness as Allah, most Majestic, most Glorious, has commanded to do?’ He replied, ‘No, I did not do so.’ He (the Imam) said, ‘Your divorce in not valid.’”
