Sahih Muslim , Book 38, Hadith 10 (In-Book) ⓘ

Jabir b. 'Abdullah reported: A child was born in the house of a person amongst us, and he gave him the name of Qasim. We said: We will not allow you (to give the name) to your child as Qasim (and thus adopt the kunya of Abu'l-Qasim) and coal your eyes. He (that person) came to Allah's Apostle and made a mention of that to him, whereupon he said: Call your son 'Abd al-Rahman.

حَدَّثَنَا عَمْرٌو النَّاقِدُ، وَمُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، جَمِيعًا عَنْ سُفْيَانَ، قَالَ عَمْرٌو حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، حَدَّثَنَا ابْنُ الْمُنْكَدِرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ وُلِدَ لِرَجُلٍ مِنَّا غُلاَمٌ فَسَمَّاهُ الْقَاسِمَ فَقُلْنَا لاَ نَكْنِيكَ أَبَا الْقَاسِمِ وَلاَ نُنْعِمُكَ عَيْنًا ‏.‏ فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَذَكَرَ ذَلِكَ لَهُ فَقَالَ ‏ "‏ أَسْمِ ابْنَكَ عَبْدَ الرَّحْمَنِ ‏" ‏ ‏.‏
