Musannaf Ibn Abi Shayba 27:240

Abu Mu'awiyah narrated to us, from al-A'mash, from Khaythama, who said: A woman passed by 'Isa ibn Maryam (peace be upon him) and said, "Blessed is the womb that carried you and the breast that nursed you." 'Isa (peace be upon him) said, "Blessed is he who read the Qur'an and followed what is in it."
