Continuation of the explanation of the report of Abu al-‘Ujlan al-Muharibi, who said:

The Shaykh : So this is Abu al-‘Ujlan al-Muharibi saying: "I was a soldier in the army of Ibn al-Zubayr," meaning when he came out demanding that people pledge allegiance to him for the caliphate. "My cousin passed away and bequeathed a camel of his for the cause of Allah." A cousin of Abu al-‘Ujlan died and had bequeathed a camel to be used in fighting in the cause of Allah. "So I said to his son," Abu al-‘Ujlan is speaking to his cousin's son, "Give me the camel." Since your father bequeathed this camel for the cause of Allah, hand over the camel to me, for I am in the army of Ibn al-Zubayr. It seems the son of Abu al-‘Ujlan's cousin was wise and sensible, as he did not rush to respond to his relative. "He said, 'Let us go to Ibn ‘Umar so we can ask him.'" They would take his opinion, as he was one of the senior Companions and one of their scholars. "So we went to Ibn ‘Umar and he said: 'O Abu ‘Abd al-Rahman, my father...'" This is the cousin of Abu al-‘Ujlan speaking to Ibn ‘Umar, saying, "O Abu ‘Abd al-Rahman." This is the kunya of ‘Abd Allah ibn ‘Umar ibn al-Khattab, Abu ‘Abd al-Rahman. He addressed him by his kunya. And this is one of the etiquettes of Islam, and I think some of this was mentioned in a previous lesson: the Islamic etiquette is that a man is not addressed by his name or by a title, but by his kunya. Therefore, we rarely find, or rather it is impossible to find, a man from the righteous Salaf who does not have a kunya. No matter if his name is Muhammad ibn Ahmad or Muhammad Isma‘il, he will have a kunya: Abu Ahmad, Abu Muhammad, Abu Salih, Abu ‘Abd al-Rahman, and so on. And this is a Sunnah that Muslims have maintained for hundreds of years, especially the non-Arabs. The non-Arabs do not know this Sunnah at all, because non-Arab customs have prevailed over them. As for the Arabs, the majority of them maintain this Sunnah to this day, because it was originally an Arab custom, and then the Messenger (peace be upon him) supported it. He gave many of his followers kunyas, even some of the women. For example, the Lady ‘Aisha (may Allah be pleased with her), although she was not blessed with children and was the wife of the Messenger (peace and blessings be upon him), seemed to feel some discomfort because she had no kunya. "So she came to the Prophet (peace and blessings be upon him) and said: 'All your wives have kunyas.' He said to her: So she took the kunya Umm ‘Abd Allah, although she had no children. From this, it is understood that it is Islamic etiquette for a Muslim to take a kunya, even if he has no children. More amazing than this is that there was a small girl who was a relative of the Messenger (peace be upon him) on the side of Khadijah . She was a child like this, so he gave her the kunya Umm Khalid. There is no harm in mentioning that I followed the Messenger in this, so I gave my daughter this kunya, Umm Khalid. So she is Umm Khalid.
