Hazrat Muhammad bin Munkadir narrates that Hazrat Jabir said: One of us had a son born to him, so he named him Qasim. Upon this, we said, "We will not call you by the kunya Abu al-Qasim, and through this we will not bring coolness to your eyes." So that person came to the service of the Messenger of Allah, peace and blessings be upon him, and mentioned this matter before him. The Messenger of Allah, peace and blessings be upon him, said: Name your son Abdur Rahman.
