Sa'id bin Mnswr bin Sh'bh سعيد بن منصور بن شعبة · Funerals (Kitab Al-Jana'iz)

When Ibrahim, the son of the Prophet (ﷺ) died, he prayed over him at the place where he used to sit. Abu Dawud said: I recited to Sa'id b. Ya'qub al-Taliqani saying: Ibn al-Mubarak transmitted to you from Ya'qub b. al-Qa'qa' on the authority of 'Ata that the Prophet (ﷺ) prayed over his son Ibrahim when he was seventeen days old.
