باب بَيَانِ أَنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ الْمُؤْمِنُونَ وَأَنَّ مَحَبَّةَ الْمُؤْمِنِينَ مِنَ الإِيمَانِ وَأَنَّ إِفْشَاءَ السَّلاَمِ سَبَبٌ لِحُصُولِهَا:

Hadith 54
Abu Hurairah (RA) reported: The Messenger of Allah (ﷺ) (may peace and blessing be upon him) observed: You shall not enter Paradise so long as you do not affirm belief (in all those things which are the articles of faith) and you will not believe as long as you do not love one another. Should I not direct you to a thing which, if you do, will foster love amongst you: (i. e.) give currency to (the practice of paying salutation to one another by saying) as-salamu alaikum.
Hadith 54
وحَدَّثَنِي
زُهَيْرُ بْنُ حَرْبٍ ، أَنْبَأَنَا
جَرِيرٌ ، عَنِ
الأَعْمَشِ ، بِهَذَا الإِسْنَادِ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : وَالَّذِي نَفْسِي بِيَدِهِ ، لَا تَدْخُلُونَ الْجَنَّةَ حَتَّى تُؤْمِنُوا ، بِمِثْلِ حَدِيثِ أَبِي مُعَاوِيَةَ ، وَوَكِيعٍ .
Zuhair bin Harb said: Jarir reported on the authority of A'mash with this chain of transmitters that the Messenger of Allah (ﷺ) observed: By him in Whose hand is my life, you shall not enter Paradise unless you believe. The rest of the hadith is the same as narrated by Abd Mu'awiyah and Waki'
