Anas reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "As-Salam (peace) is one of the Names of Allah Almighty which Allah has placed in the earth. Therefore give the greeting among yourselves."
حَدَّثَنَا شِهَابٌ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللهِ صلى الله عليه وسلم: إِنَّ السَّلامَ اسْمٌ مِنْ أَسْمَاءِ اللهِ تَعَالَى، وَضَعَهُ اللَّهُ فِي الأَرْضِ، فَأَفْشُوا السَّلامَ بَيْنَكُمْ.
