Musannaf Ibn Abi Shayba 8:2949

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from Isma’il bin Umayyah, from Muzahim bin Abi Muzahim, from ‘Abd al-‘Aziz bin ‘Abd Allah bin Khallad bin Usayd, from Muhrish, that the Prophet (may Allah bless him and grant him peace) performed ‘Umrah from al-Ji’ranah, then he returned to it as one who spends the night. He said: And I saw his back as if it were a bar of silver.
