It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Do not combine my name and my kunyah, for indeed I am Abu al-Qasim; Allah grants and I distribute.
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) was in Baqi‘ when a man called out: "O Abu al-Qasim!" When the Prophet (peace and blessings be upon him and his family) turned towards him, the man said: "I did not mean you." The Prophet (peace and blessings be upon him and his family) said: "Take my name, but do not take my kunya."
It is narrated from Sayyiduna Jabir bin Abdullah Ansari (may Allah be pleased with him) that a boy was born to an Ansari. He wanted to name him Muhammad, so he came to the Noble Prophet (peace and blessings be upon him) and asked him. The Prophet (peace and blessings be upon him) said: The Ansar have done well; name him with my name, but do not use my kunya.
It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him), he says: A child was born to one of us, he named him Qasim. We said to him: We will not give you the kunyah (patronymic) Abu al-Qasim, nor will we thus cool your eyes. So he went to the Noble Prophet (peace and blessings be upon him) and informed him of this matter. The Prophet (peace and blessings be upon him) said: Name your son Abdur Rahman.
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Name yourselves after me, but do not take my kunya. I am Abu al-Qasim.
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: Whoever names (his child) after my name, should not take my kunya, and whoever takes my kunya, should not take my name.
Abdur Rahman bin Abi Laila says: Sayyiduna Umar (may Allah be pleased with him) looked towards Abu Abdur Hamid or Ibn Abdur Hamid, whose name was Muhammad. A man was abusing him and saying: "O Muhammad! May Allah do such and such to you, and such and such, and such and such." At that moment, the Commander of the Faithful said: "O Ibn Zaid! Come closer to me. Am I seeing that because of you, Muhammad (peace and blessings be upon him) is being insulted? No, by Allah, as long as you are alive, you will not be called Muhammad." Then he named him Abdur Rahman. Then the Commander of the Faithful sent a message to the Banu Talha that those among them whose names were Muhammad should change their names. There were a total of seven such individuals, and even the chief and elder among them was named Muhammad. Among them, Sayyiduna Muhammad bin Talha (may Allah be pleased with him) said: "O Commander of the Faithful! I beseech you by Allah, do not change my name, because my name was given by Muhammad (peace and blessings be upon him) himself." Upon hearing this, Sayyiduna Umar (may Allah be pleased with him) said: "Go, I have no authority regarding the one whose name was given by Muhammad (peace and blessings be upon him) himself."
