We were sitting in the company of Allah's Apostle ﷺ that Sura al-Jumu'a was revealed to him and when he recited (these words):" Others from amongst them who have not yet joined them," a person amongst them (those who were sitting there) said: Messenger of Allah! But Allah's Apostle ﷺ made no reply, until he questioned him once, twice or thrice. And there was amongst us Salman the Persian. The Apostle of Allah ﷺ placed his hand on Salman and then said: Even if faith were near the Pleiades, a man from amongst these would surely find it. (Using translation from Muslim 2546b)  

كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ ﷺ إِذْ نَزَلَتْ سُورَةُ الْجُمُعَةِ فَلَمَّا قَرَأَ {وَآخَرِينَ مِنْهُمْ لَمَّا يَلْحَقُوا بِهِمْ} [الجمعة 3] قَالَ مَنْ هَؤُلَاءِ يَا رَسُولَ اللهِ؟ فَلَمْ يُرَاجِعْهُ النَّبِيُّ ﷺ حَتَّى سَأَلَهُ مَرَّةً أَوْ مَرَّتَيْنِ أَوْ ثَلَاثًا قَالَ وَفِينَا سَلْمَانُ الْفَارِسِيُّ فَوَضَعَ النَّبِيُّ ﷺ يَدَهُ عَلَى سَلْمَانَ ثُمَّ قَالَ «لَوْ كَانَ الْإِيمَانُ عِنْدَ الثُّرَيَّا لَنَالَهُ رِجَالٌ مِنْ هَؤُلَاءِ»  

[Machine] We were with the Messenger of Allah ﷺ on Friday when a caravan carrying food passed by. The people went out to meet twelve men and the verse of Al-Jumu'ah was revealed.  

كُنَّا مَعَ رَسُولِ اللهِ ﷺ فِي الْجُمُعَةِ فَمَرَّتْ عِيرٌ تَحْمِلُ الطَّعَامَ فَخَرَجَ النَّاسُ إِلَى اثْنَيْ عَشَرَ رَجُلًا فَنَزَلَتْ آيَةُ {الْجُمُعَةِ} [الجمعة 9]
