Hazrat Jabir bin Abdullah Ansari (may Allah be pleased with him) narrated that a child was born in our tribe, and they named him Qasim. The Ansar said, "We will never call you by the kunya Abu al-Qasim, and we will not give you this comfort." Hearing this, that Ansari came to the Prophet (peace be upon him) and said, "O Messenger of Allah! A child has been born in my house, and I have named him Qasim, but the Ansar say, 'We will not call you by the kunya Abu al-Qasim, and we will not give you this comfort.'" The Prophet (peace be upon him) said, "The Ansar have spoken correctly. Name after my name, but do not take my kunya, because I am al-Qasim."
