(27) باب مَنِ اسْتَعَانَ عَبْدًا أَوْ صَبِيًّا
Narrated `Abdul-`Aziz:
Anas said, "When Allah's Messenger (ﷺ) arrived at Medina, Abu Talha took hold of my hand and brought me to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Anas is an intelligent boy, so let him serve you." Anas added, "So I served the Prophet (ﷺ) L at home and on journeys; by Allah, he never said to me for anything which I did: Why have you done this like this or, for anything which I did not do: 'Why have you not done this like this?"
