Ali ibn Babawayh Qummi

Ali ibn Babawayh al-Qummi (Arabic: عَلِيّ بْن بَابَوَيْه ٱلْقُمِيّ, romanized: ʿAlī ibn Bābawayh al-Qummī; died 939) was a Twelver Shi'a scholar from the time of the Ghaybat al-Sughra.[1] He's the father of Shaykh Saduq.

He wrote a letter to Imam Muhammad al-Mahdi, asking for prayer for him to have a child, as doctors had told him he could not have one. Thus his son, Shaykh Saduq, was always called: "Oh you that was born by the prayer of Imam Mahdi!".
