The Prophet ﷺ said: On the Day of Resurrection you will be called by your names and by your father's names, so give yourselves good names.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّكُمْ تُدْعَوْنَ يَوْمَ الْقِيَامَةِ بِأَسْمَائِكُمْ وَأَسْمَاءِ آبَائِكُمْ فَأَحْسِنُوا أَسْمَاءَكُمْ  

Your names which are dearest to Allah are ‘Abd Allah and ‘Abd al-Rahman.  

قَالَ رَسُولُ اللَّهِ ﷺ أَحَبُّ الأَسْمَاءِ إِلَى اللَّهِ تَعَالَى عَبْدُ اللَّهِ وَعَبْدُ الرَّحْمَنِ  

The Prophet ﷺ said: Call yourselves by the names of the Prophets. The names dearest to Allah are Abdullah and AbdurRahman, the truest are Harith and Hammam, and the worst are Harb and Murrah.  

عَنْ أَبِي وَهْبٍ الْجُشَمِيِّ وَكَانَتْ لَهُ صُحْبَةٌ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ تَسَمَّوْا بِأَسْمَاءِ الأَنْبِيَاءِ وَأَحَبُّ الأَسْمَاءِ إِلَى اللَّهِ عَبْدُ اللَّهِ وَعَبْدُ الرَّحْمَنِ وَأَصْدَقُهَا حَارِثٌ وَهَمَّامٌ وَأَقْبَحُهَا حَرْبٌ وَمُرَّةُ  

Have you some dates? I said : Yes. I then gave him some dates which he put in his mouth, chewed them, opened his mouth and them in it. The baby began to lick them. The prophet (May peace be upon him) said: ANSAR’s favourite (fruit) is dates. And he gave him the name of ‘Abd al-Rahman.  

ذَهَبْتُ بِعَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ إِلَى النَّبِيِّ ﷺ حِينَ وُلِدَ وَالنَّبِيُّ ﷺ فِي عَبَاءَةٍ يَهْنَأُ بَعِيرًا لَهُ قَالَ هَلْ مَعَكَ تَمْرٌ قُلْتُ نَعَمْ قَالَ فَنَاوَلْتُهُ تَمَرَاتٍ فَأَلْقَاهُنَّ فِي فِيهِ فَلاَكَهُنَّ ثُمَّ فَغَرَ فَاهُ فَأَوْجَرَهُنَّ إِيَّاهُ فَجَعَلَ الصَّبِيُّ يَتَلَمَّظُ فَقَالَ النَّبِيُّ ﷺ حِبُّ الأَنْصَارِ التَّمْرُ وَسَمَّاهُ عَبْدَ اللَّهِ
