عَنْ مُعَاذِ بْنِ جَبَلٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ السَّلَامُ تَحِيَّةُ أَهْلِ الْجَنَّةِ
Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Saying Salam will be the gift of the people of Paradise.
