Sahih al-Bukhari, Hadith 6186 ⓘ

Narrated Jabir: 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 was informed about that, and he said, "Name your son `Abdur-Rahman."

حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا ابْنُ عُيَيْنَةَ، حَدَّثَنَا ابْنُ الْمُنْكَدِرِ، عَنْ جَابِرٍ ـ رضى الله عنه ـ قَالَ وُلِدَ لِرَجُلٍ مِنَّا غُلاَمٌ فَسَمَّاهُ الْقَاسِمَ فَقُلْنَا لاَ نَكْنِيكَ أَبَا الْقَاسِمِ وَلاَ كَرَامَةَ‏.‏ فَأَخْبَرَ النَّبِيَّ صلى الله عليه وسلم فَقَالَ ‏ "‏ سَمِّ ابْنَكَ عَبْدَ الرَّحْمَنِ ‏" ‏‏.‏
