I was with the Prophet ﷺ in the Cave. When I raised my head, I saw the feet of the people. I said, "O Messenger of Allah ﷺ! If some of them should look down, they will see us." The Prophet ﷺ said, "O Abu Bakr, be quiet! (For we are) two and Allah is the Third of us."
كُنْتُ مَعَ النَّبِيِّ ﷺ فِي الْغَارِ فَرَفَعْتُ رَأْسِي فَإِذَا أَنَا بِأَقْدَامِ الْقَوْمِ فَقُلْتُ يَا نَبِيَّ اللَّهِ لَوْ أَنَّ بَعْضَهُمْ طَأْطَأَ بَصَرَهُ رَآنَا قَالَ اسْكُتْ يَا أَبَا بَكْرٍ اثْنَانِ اللَّهُ ثَالِثُهُمَا
