Volume 1, Book 4, Number 189:
Narrated As-Sa’ib bin Yazid:
My aunt took me to the Prophet and said, “O Allah’s Apostle! This son of my sister has got a disease
in his legs.” So he passed his hands on my head and prayed for Allah’s blessings for me; then he per –
formed ablution and I drank from the remaining water. I stood behind him and saw the seal of
Prophethood between his shoulders, and it was like the “Zir-al-Hijla” (means the button of a small
tent, but some said ‘egg of a partridge.’ etc.)
