When Abu Huraira accompanied by his slave set out intending to embrace Islam they lost each other on the way. The slave then came while Abu Huraira was sitting with the Prophet. The Prophet ﷺ said, "O Abu Huraira! Your slave has come back." Abu Huraira said, "Indeed, I would like you to witness that I have manumitted him." That happened at the time when Abu Huraira recited (the following poetic verse):-- 'What a long tedious tiresome night! Nevertheless, it has delivered us From the land of Kufr (disbelief).  

أَنَّهُ لَمَّا أَقْبَلَ يُرِيدُ الإِسْلاَمَ وَمَعَهُ غُلاَمُهُ ضَلَّ كُلُّ وَاحِدٍ مِنْهُمَا مِنْ صَاحِبِهِ فَأَقْبَلَ بَعْدَ ذَلِكَ وَأَبُو هُرَيْرَةَ جَالِسٌ مَعَ النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ يَا أَبَا هُرَيْرَةَ هَذَا غُلاَمُكَ قَدْ أَتَاكَ فَقَالَ أَمَا إِنِّي أُشْهِدُكَ أَنَّهُ حُرٌّ قَالَ فَهُوَ حِينَ يَقُولُ يَا لَيْلَةً مِنْ طُولِهَا وَعَنَائِهَا عَلَى أَنَّهَا مِنْ دَارَةِ الْكُفْرِ نَجَّتِ  

On my way to the Prophet ﷺ I was reciting:-- 'What a long tedious tiresome night! Nevertheless, it has saved us From the land of Kufr (disbelief).' I had a slave who ran away from me on the way. When I went to the Prophet ﷺ and gave the pledge of allegiance for embracing Islam, the slave showed up while I was still with the Prophet ﷺ who remarked, "O Abu Huraira! Here is your slave!" I said, "I manumit him for Allah's Sake," and so I freed him.  

لَمَّا قَدِمْتُ عَلَى النَّبِيِّ ﷺ قُلْتُ فِي الطَّرِيقِ يَا لَيْلَةً مِنْ طُولِهَا وَعَنَائِهَا عَلَى أَنَّهَا مِنْ دَارَةِ الْكُفْرِ نَجَّتِ قَالَ وَأَبَقَ مِنِّي غُلاَمٌ لِي فِي الطَّرِيقِ قَالَ فَلَمَّا قَدِمْتُ عَلَى النَّبِيِّ ﷺ بَايَعْتُهُ فَبَيْنَا أَنَا عِنْدَهُ إِذْ طَلَعَ الْغُلاَمُ فَقَالَ لِي رَسُولُ اللَّهِ ﷺ يَا أَبَا هُرَيْرَةَ هَذَا غُلاَمُكَ فَقُلْتُ هُوَ حُرٌّ لِوَجْهِ اللَّهِ فَأَعْتَقْتُهُ لَمْ يَقُلْ أَبُو كُرَيْبٍ عَنْ أَبِي أُسَامَةَ حُرٌّ  

When Abu Huraira accompanied by his slave came intending to embrace Islam, they lost each other on the way. (When the slave showed up) Abu Huraira said (to the Prophet), "I make you witness that the slave is free for Allah's Cause."  

لَمَّا أَقْبَلَ أَبُو هُرَيْرَةَ ؓ وَمَعَهُ غُلاَمُهُ وَهْوَ يَطْلُبُ الإِسْلاَمَ فَأَضَلَّ أَحَدُهُمَا صَاحِبَهُ بِهَذَا وَقَالَ أَمَا إِنِّي أُشْهِدُكَ أَنَّهُ لِلَّهِ
