Chapter: "Name yourselves by my name, but do not call yourselves by my Kunyah."
Narrated Jabir bin `Abdullah: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."

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 ".
