Tufail bin ʿAmr came to the Prophet ﷺ and said, "The Daus (nation) have perished as they disobeyed and refused to accept Islam. So invoke Allah against them." But the Prophet ﷺ said, "O Allah! Give guidance to the Daus (tribe) and bring them (to Islam)!"  

جَاءَ الطُّفَيْلُ بْنُ عَمْرٍو إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ دَوْسًا قَدْ هَلَكَتْ عَصَتْ وَأَبَتْ فَادْعُ اللَّهَ عَلَيْهِمْ فَقَالَ اللَّهُمَّ اهْدِ دَوْسًا وَأْتِ بِهِمْ  

When I came to the Prophet ﷺ said on my way, "O what a long tedious tiresome night; nevertheless, it has rescued me from the place of Heathenism." A slave of mine ran away on the way. When I reached the Prophet ﷺ I gave him the oath of allegiance (for Islam), and while I was sitting with him, suddenly the slave appeared. The Prophet ﷺ said to me. "O Abu Huraira! Here is your slave," I said, "He (i.e. the slave) is (free) for Allah's Sake," and manumitted him.  

لَمَّا قَدِمْتُ عَلَى النَّبِيِّ ﷺ قُلْتُ فِي الطَّرِيقِ يَا لَيْلَةً مِنْ طُولِهَا وَعَنَائِهَا عَلَى أَنَّهَا مِنْ دَارَةِ الْكُفْرِ نَجَّتِ وَأَبَقَ غُلاَمٌ لِي فِي الطَّرِيقِ فَلَمَّا قَدِمْتُ عَلَى النَّبِيِّ ﷺ فَبَايَعْتُهُ فَبَيْنَا أَنَا عِنْدَهُ إِذْ طَلَعَ الْغُلاَمُ فَقَالَ لِي النَّبِيُّ ﷺ يَا أَبَا هُرَيْرَةَ هَذَا غُلاَمُكَ فَقُلْتُ هُوَ لِوَجْهِ اللَّهِ تَعَالَى فَأَعْتَقْتُهُ
