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  

[Machine] Narrated by Abu Wahb Al-Jushami, who had companionship, he said: The Messenger of Allah ﷺ said, "Call yourselves by the names of the Prophets: the dearest of names to Allah are Abdullah and Abdur-Rahman, and the most truthful are Harith and Hammam. The ugliest are Harb and Murrah. Connect yourselves with horses and touch their manes, and stroke their forelocks (for luck), and do what is suitable for them, but do not overstep the limits, and do not overstep the limits in the case of exploiting or reading the stars. And be cautious of wearing clothes made of silk, for whoever wears it in this world will not wear it in the Hereafter."  

عَنْ أَبِي وَهْبٍ الْجُشَمِيِّ وَكَانَتْ لَهُ صُحْبَةٌ قَالَ قَالَ رَسُولُ اللهِ ﷺ «تَسَمُّوا بِاسْمِ الْأَنْبِيَاءِ أَحَبُّ الْأَسْمَاءِ إِلَى اللهِ عَبْدُ اللهِ وَعَبْدُ الرَّحْمَنِ وَأَصْدَقُهَا حَارِثٌ وَهَمَّامٌ وأَقْبَحُهَا حَرْبٌ وَمُرَّةَ وَارْتَبِطُوا الْخَيْلَ وَامْسَحُوا بِنَوَاصِيهَا وَأَعْجَازِهَا أَوْ قَالَ وَأَكْفَالِهَا وَقَلِّدُوهَا وَلَا تُقَلِّدُوهَا الْأَوْتَارَ وَعَلَيْكُمْ بِكُلٍّ كُمَيْتٍ أَغَرَّ مُحَجَّلٍ أَوْ أَشْقَرَ أَغَرَّ مُحَجَّلٍ أَوْ أَدْهَمَ أَغَرَّ مُحَجَّلٍ»  

"سَمُّوا بِأَسْمَاءِ الأَنْبِياءِ، وَأَحَبُّ الأَسْمَاءِ إِلَى اللهِ: عَبْدُ اللهِ، وَعَبْدُ الرَّحْمن، وَأَصْدَقُهَا، حَارِثٌ، وَهَمَّامٌ، وَأقْبَحُهَا حَرْبٌ وَمُرَّةٌ".
