Narrated Jabir:
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 " .
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."
