Read the English translation first, with the original Arabic directly underneath.
It was narrated from Abu Hurairah(RA) that the Messenger of Allah(ﷺ) said:
"By the One in Whose Hand is my soul, you will not enter Paradise until you believe, and you will not believe until you love one another. Shall I not tell you of something which, if you do it, you will love one another? Spread (the greeting of) peace among yourselves.'"
وَالَّذِي نَفْسِي بِيَدِهِ لاَ تَدْخُلُوا الْجَنَّةَ حَتَّى تُؤْمِنُوا وَلاَ تُؤْمِنُوا حَتَّى تَحَابُّوا . أَوَلاَ أَدُلُّكُمْ عَلَى شَىْءٍ إِذَا فَعَلْتُمُوهُ تَحَابَبْتُمْ أَفْشُوا السَّلاَمَ بَيْنَكُمْ
