'Abdullah bin Salam (RAA) narrated that the Messenger of Allah (ﷺ) said:

“O people, extend greetings (saying Salam to each other), keep relations with your kin, provide food (to people) and pray at night when people are asleep and you will enter Paradise in peace.” Related by At-Tirmidhi who graded it as Sahih.

وَعَنْ عَبْدِ اَللَّهِ بْنِ سَلَّامٍ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ يَا أَيُّهَا اَلنَّاسُ! أَفْشُوا اَلسَّلَام, وَصِلُوا اَلْأَرْحَامَ, وَأَطْعِمُوا اَلطَّعَامَ, وَصَلُّوا بِاللَّيْلِ وَالنَّاسُ نِيَامٌ, تَدْخُلُوا اَلْجَنَّةَ بِسَلَامٍ } أَخْرَجَهُ اَلتِّرْمِذِيُّ وَصَحَّحَهُ .‏ [1]‏ .‏
