question #3 Sahih al-Bukhari 6186, Book 78, Hadith 210 : What is the significance of the name ‘Abdur-Rahman’ in Islam?

A boy was born for a man among us, and the man named him Al-Qasim. We said to him, “We will not
call you Abu-l-Qasim, nor will we respect you for that.” The Prophet (ﷺ) was informed about that, and he
said, “Name your son `Abdur-Rahman.”
