He was orphaned at the tender age of 6 and yet surrounded by those who loved and cared for him, supported him throughout his life, and stood by his side with every trial that afflicted him.
Thus he understood that no child should ever grow up without the warmth and love of family and so he often played with the orphan children and consoled their hearts. He had a special soft spot for orphans and called towards the adoption and protection of them and kind treatment to them.
So much so that he stated,
“I and the custodian of an orphan are like this (together) in Paradise”, and he joined his forefinger and middle finger together. (Bukhari)
