from Abu Hurairah that the Prophet ﷺ said: "The rider gives the Salam to the walking person, and the walking person to the sitting person and the few to the many." Ibn Al-Muthanna added in his narration: "And the young one gives the Salam to the elder."  

عَنِ النَّبِيِّ ﷺ قَالَ يُسَلِّمُ الرَّاكِبُ عَلَى الْمَاشِي وَالْمَاشِي عَلَى الْقَاعِدِ وَالْقَلِيلُ عَلَى الْكَثِيرِ وَزَادَ ابْنُ الْمُثَنَّى فِي حَدِيثِهِ وَيُسَلِّمُ الصَّغِيرُ عَلَى الْكَبِيرِ وَفِي الْبَابِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ شِبْلٍ وَفَضَالَةَ بْنِ عُبَيْدٍ وَجَابِرٍ  

from Abu Hurairah that the Prophet ﷺ said: "The young one gives the Salam to the elder, the one passing the by to the one sitting and the few to the many."  

عَنِ النَّبِيِّ ﷺ قَالَ يُسَلِّمُ الصَّغِيرُ عَلَى الْكَبِيرِ وَالْمَارُّ عَلَى الْقَاعِدِ وَالْقَلِيلُ عَلَى الْكَثِيرِ قَالَ وَهَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ  

that the Messenger of Allah ﷺ said: "The horseman gives Salam to the walking person, the walking person to the one standing and the few to the many."  

عَنْ أَبِي عَلِيٍّ الْجَنْبِيِّ عَنْ فَضَالَةَ بْنِ عُبَيْدٍ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يُسَلِّمُ الْفَارِسُ عَلَى الْمَاشِي وَالْمَاشِي عَلَى الْقَائِمِ وَالْقَلِيلُ عَلَى الْكَثِيرِ
