The finest form of dutifulness is maintaining relations with those whom one’s father loved

When Ibn ‘Umar (may Allah be pleased with him) would leave to Makkah to perform Hajj, he would bring along with him a donkey to rest on when he became tired of riding the camel. Once, he met a Bedouin and asked him: "Are you so and so the son of so and so?" He said: 'Yes.' So, Ibn ‘Umar dismounted from his donkey and said: "Take this and ride it," and he gave him a turban that was tied on his head and said to him: "Tie your head with this."

It was said to ‘Abdullāh ibn ‘Umar: "May Allah guide you!" or "May Allah forgive you!" These people are Bedouins, and Bedouins are satisfied with much less – meaning why would you leave your donkey and walk on your feet and give him your turban that you wrap your head with, while he is a Bedouin who would be satisfied with much less? Ibn ‘Umar replied: "The finest form of dutifulness is maintaining relations with those whom one’s father loved."

This means that it is from dutifulness that if someone’s father, mother, or relative passes away, that he shows kindness to those whom they loved, and this is not only restricted to their friends, but even their friends' relatives. He then said: "and this man's father was a friend of ‘Umar", meaning ‘Umar ibn al-Khattāb, his father. Because he was a friend of his father, he was kind and generous to him out of dutifulness to his own father ‘Umar (may Allah be pleased with him).
