كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍۢ وَٱلْأَحْزَابُ مِنۢ بَعْدِهِمْ ۖ وَهَمَّتْ كُلُّ أُمَّةٍۭ بِرَسُولِهِمْ لِيَأْخُذُوهُ ۖ وَجَٰدَلُوا۟ بِٱلْبَٰطِلِ لِيُدْحِضُوا۟ بِهِ ٱلْحَقَّ فَأَخَذْتُهُمْ ۖ فَكَيْفَ كَانَ عِقَابِ
The folk of Noah and the factions after them denied (their messengers) before these, and every nation purposed to seize their messenger and argued falsely, (thinking) thereby to refute the Truth. Then I seized them, and how (awful) was My punishment.

Chapter: The story of Daus and Tufail bin ‘Amr Ad-Dausi
Narrated Abu Huraira:
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.
