Arabic hadith text
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، حَدَّثَنَا أَبُو الزِّنَادِ، أَنَّ الأَعْرَجَ، حَدَّثَهُ أَنَّهُ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ إِنَّهُ سَمِعَ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ "نَحْنُ الآخِرُونَ السَّابِقُونَ يَوْمَ الْقِيَامَةِ "وَبِإِسْنَادِهِ " لَوِ اطَّلَعَ فِي بَيْتِكَ أَحَدٌ وَلَمْ تَأْذَنْ لَهُ، خَذَفْتَهُ بِحَصَاةٍ فَفَقَأْتَ عَيْنَهُ، مَا كَانَ عَلَيْكَ مِنْ جُنَاحٍ "
Translation
Narrated Abu Huraira
That he heard Allah's Messenger (ﷺ) saying, "We (Muslims) are the last (to come) but (will be) the foremost (on the Day of Resurrection)." And added, "If someone is peeping (looking secretly) into your house without your permission, and you throw a stone at him and destroy his eyes, there will be no blame on you."
