What was the age of Ishmael (peace be upon him) when Abraham (peace be upon him) left him, and how old was he when Abraham saw him again after a year?

Ismail (peace be upon him) was two years old when he was left in Mecca with his mother Hagar. His age at the first sighting of him by Abraham thereafter was not specified. It was said that Abraham used to visit him and Hagar every month on Al-Buraq, which indicates that he came to him several times before his marriage.
