This woman was the daughter of 'Umar Ibn Yazid, one of the companions of Imam al-Sadiq ('a). Shaykh al-Tusi has introduced three men with this name as the companions of Imam al-Sadiq ('a).1 In studying the books, it was not clear which 'Umar Ibn Yazid he was.

She has related traditions from her father 'Umar Ibn Yazid; and his paternal cousin has related traditions from her.

Shaykh al-Kulayni relying on his sources relates a tradition from 'Umar Ibn Yazid's cousin from Bint (the daughter of) 'Umar Ibn Yazid from her father from Imam al-Sadiq ('a) as saying, "Whenever one of you wants to drink some water, say: 'In the Name of God,' and then drink. Then, pause and say: 'Praise the Lord.' Then, drink and say: 'In the Name of God.' Again pause and say: 'Praise the Lord.' Drink and say: 'In the Name of God.' Pause and again say: 'Praise the Lord.' This water will continue to praise the Lord till the time it is in your body."2
