[Machine] The Prophet ﷺ said to Ubayy, "Indeed, I will recite a Surah to you." Ubayy then asked him, "Were you commanded to do so by Allah?" He replied, "Yes." So he recited the verse, "{Those who disbelieved among the People of the Scripture and the polytheists were not to be parted [from disbelief] until there came to them clear evidence - a Messenger from Allah, reciting purified scriptures}" (Surah Al-Bayyinah, verse 2).  

أَنَّ النَّبِيَّ ﷺ قَالَ لِأُبَيٍّ «إِنِّي أُقْرِئُكَ سُورَةً» فَقَالَ لَهُ أُبَيٌّ أُمِرْتَ بِذَاكَ بِأَبِي أَنْتَ؟ قَالَ «نَعَمْ» فَقَرَأَ {لَمْ يَكُنِ الَّذِينَ كَفَرُوا مِنْ أَهْلِ الْكِتَابِ وَالْمُشْرِكِينَ مُنْفَكِّينَ حَتَّى تَأْتِيَهُمُ الْبَيِّنَةُ رَسُولٌ مِنَ اللَّهِ يَتْلُو صُحُفًا مُطَهَّرَةً} [البينة 2]
