[Machine] A woman went to the Prophet ﷺ and said, "O Messenger of Allah, I have given birth to a boy and I named him Muhammad and I gave him the kunya of Abu Al-Qasim. I heard that you dislike that." So the Prophet asked, "What is it that makes my name allowed and my kunya forbidden? Or what is it that makes my kunya forbidden and my name allowed? " The scholar, may Allah have mercy on him, said, "The Hadiths that prohibit using the kunya of Abu Al-Qasim in general are more authentic than this Hadith of Al-Hajabi and others. So the ruling is in her favor. And the Hadith of Ali indicates that he recognized the prohibition until he asked for permission to use it alone. And perhaps the Hadith of Aisha also implies, if its chain is correct, that the prohibition occurred at the initial stage and not on a permanent basis. When the woman assumed that it was permanently forbidden, it was clear that it was not forbidden but disliked. And Allah knows best. Indeed, Humaid ibn Zanjaway said in his book Al-Adab, "I asked Ibn Abi Uways about Malik's opinion on a person combining the name of the Prophet and his kunya. He pointed to a sheikh sitting with us and said, "This is Muhammad ibn Malik. They named him Muhammad and gave him the kunya of Abu Al-Qasim. And he used to say that in the lifetime of the Prophet, it was disliked to be called by his kunya, but it was not disliked to be called by his name, because hardly anyone would call themselves by his name. But when he passed away, it was allowed. Don't you see that he allowed Ali, if he had a son after him, to combine both the name and the kunya? And among the sons of the companions who combined both were Muhammad ibn Abu Bakr, Muhammad ibn Jafar ibn Abu Talib, Muhammad ibn Sa'd ibn Abu Waqqas, Muhammad ibn Hattib, and Muhammad ibn Al-Muntashir." The sheikh said, "This is a specific ruling during his lifetime and an evidence for those who combined them after his death of the type that Al-Shafi'i, may Allah have mercy on him, used to say, "There is no evidence in the statement of anyone along with the Prophet." And Allah knows best.
