The Ruling on Taking the Name of the Prophet (peace and blessings be upon him) and Using His Kunya

Question:
From Yemen - Sana'a. This is a letter sent by one of the brothers from there, saying: Muhammad Fatah Allah Salim al-Samim -it appears- is a teacher of Islamic and Arabic subjects at the scientific institutes in Sana'a. Our brother asks and says at the beginning of his letter:
In the name of Allah, the Most Gracious, the Most Merciful. To the honorable Shaykh Abdul Aziz ibn Baz, the General President of the Committee for Ifta, Da'wah, and Guidance in the Kingdom of Saudi Arabia. Peace be upon you, and Allah's mercy and blessings, and may Allah the Exalted preserve you and guide you to fulfill the message of Islam and the Muslims. Honorable Shaykh! I read in the chapter "What Came Regarding Names and Kunyas," pages (626, 627), of the book Fath al-Ghaffar, which contains the rulings of the Sunnah of our chosen Prophet (peace and blessings be upon him), by the judge and scholar Sharaf al-Din al-Hasan ibn Ahmad al-Raba'i al-Yemeni (may Allah have mercy on him), a collection of hadiths in the aforementioned chapter. I do not know whether the prohibition therein is something that must be acted upon, or whether other hadiths contradict that, thereby permitting naming with his name (peace and blessings be upon him) and using his kunya? And if someone named his son Qasim or al-Qasim, is it permissible for him, when calling his son by his name, to say "O Abu al-Qasim" or "O Abu Qasim"? To clarify this, these are the hadiths reported in this matter. From Abu Hurayrah (may Allah be pleased with him) : that the Prophet (peace and blessings be upon him) said: , agreed upon by al-Bukhari and Muslim.
And from 'Ali (may Allah be pleased with him) he said: "O Messenger of Allah! What do you say if a child is born to me after you, should I name him Muhammad and give him your kunya?" He said: "Yes, so it was a dispensation for me." Al-Tirmidhi narrated it and said: It is a good, authentic hadith.
And from A'isha (may Allah be pleased with her) she said: "A woman came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I gave birth to a boy and named him Muhammad and gave him the kunya Abu al-Qasim. It was mentioned to me that you dislike that. He said: Abu Dawud narrated it, and al-Mundhiri said: Strange. We hope you will benefit us with your opinion regarding that? May Allah reward you with the best reward.

Answer:
The correct view in this is what is established from the Prophet (peace and blessings be upon him) that he said: And this is, according to the scholars, during his lifetime (peace and blessings be upon him); because if he is called Abu al-Qasim, it may cause confusion among people. Perhaps if he hears it, he might turn around thinking he is the one being called, while the one being called is someone else.
As for taking his name, there is no harm in it during his lifetime and after his passing (peace and blessings be upon him). The Siddiq (may Allah be pleased with him) named his son Muhammad during the lifetime of the Prophet (peace and blessings be upon him); in the Farewell Pilgrimage, he named him Muhammad. And among the Companions was Muhammad ibn Muslimah, and the Prophet (peace and blessings be upon him) did not change it. So taking his name has no harm. He only prohibited his kunya, Abu al-Qasim, and then permitted it after his passing (peace and blessings be upon him) for Ali. The permission for Ali is a permission for the people; because the concern was removed. When he passed away (peace and blessings be upon him), the difficulty was removed, and the concern was removed. So there is no harm in taking his name, and there is no harm in using his kunya after his passing (peace and blessings be upon him). As for his name, there is no harm in it absolutely, even during his lifetime (peace and blessings be upon him).
As for the kunya, it was prohibited during his lifetime (peace and blessings be upon him), and then after his passing... it is a dispensation, just as the Prophet (peace and blessings be upon him) granted a dispensation in it. And because the cause for which the prohibition of using his kunya during his lifetime was established has been removed by his death (peace and blessings be upon him). And by this it is known that, and praise be to Allah, there is no harm, neither in taking his name, nor in using his kunya, upon him from his Lord the best of prayers and blessings.
