Narrated Jabir bin `Abdullah:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ ، حَدَّثَنَا سُفْيَانُ ، قَالَ سَمِعْتُ ابْنَ الْمُنْكَدِرِ ، قَالَ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما وُلِدَ لِرَجُلٍ مِنَّا غُلاَمٌ فَسَمَّاهُ الْقَاسِمَ فَقَالُوا لاَ نَكْنِيكَ بِأَبِي الْقَاسِمِ، وَلاَ نُنْعِمُكَ عَيْنًا. فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَذَكَرَ ذَلِكَ لَهُ فَقَالَ " أَسْمِ ابْنَكَ عَبْدَ الرَّحْمَنِ " .
A man among us begot a boy whom he named Al-Qasim. The people said (to him), "We will not call you Abul-l-Qasim, nor will we please you by calling you so." The man came to the Prophet (ﷺ) and mentioned that to him. The Prophet (ﷺ) said to him, "Name your son `Abdur-Rahman."
