We will not allow You to give the name of Muhammad (to your child) after the name of Messenger of Allah ﷺ. He set forth with his son carrying him on his back and came to Allah's Apostle ﷺ, and said: Messenger of Allah a son has been born to me and I have given him the name after the name of Messenger of Allah ﷺ, whereupon Messenger of Allah ﷺ said: Give him my name but do not give him my kunya, for I am Qasim in the sense that I distribute (the spoils of war) and the dues of Zakat amongst you. (Using translation from Muslim 2133a)
لَهُ قَوْمُهُ لَا نَدَعُكَ تُسَمِّي بِاسْمِ رَسُولِ اللهِ ﷺ فَانْطَلَقَ بِابْنِهِ حَامِلَهُ عَلَى ظَهْرِهِ فَأَتَى بِهِ رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ وُلِدَ لِي غُلَامٌ فَسَمَّيْتُهُ مُحَمَّدًا فَقَالَ لِي قَوْمِي لَا نَدَعُكَ تُسَمِّي بِاسْمِ رَسُولِ اللهِ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ تَسَمَّوْا بِاسْمِي وَلَا تَكْتَنُوا بِكُنْيَتِي فَإِنَّمَا أَنَا قَاسِمٌ أَقْسِمُ بَيْنَكُمْ
