[Machine] The Messenger of Allah ﷺ said, "When one of you enters a gathering in which there are people, let him greet them. And if he sits with them, then when he gets up, let him greet what is closest before the farthest."  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا جَاءَ أَحَدُكُمْ إِلَى الْمَجْلِسِ فِيهِ الْقَوْمُ فَلْيُسَلِّمْ فَإِنْ جَلَسَ مَعَهُمْ فَإِذَا قَامَ فَلْيُسَلِّمْ مَا يَجْعَلُ الْأُولَى أَوْلَى مِنَ الْآخِرَةِ»  

that the Messenger of Allah ﷺ said: "When one of you arrives at the gathering, then give the Salam, and if he is given a place to sit, then let him sit. Then when he stands, let him give the Salam, the first is more worthy than the last." (Using translation from Tirmidhī 2706)   

قَالَ رَسُولُ اللهِ ﷺ «إِذَا انْتَهَى أَحَدُكُمْ إِلَى الْمَجْلِسِ فَلْيُسَلِّمْ فَإِنْ بَدَا لَهُ أَنْ يَجْلِسَ فَلْيَجْلِسْ ثُمَّ إِذَا قَامَ فَلْيُسَلِّمْ فَلَيْسَتِ الْأُولَى بِأَحَقَّ مِنَ الْآخِرَةِ» اللَّفْظُ لِقُتَيْبَةَ خَالَفَهُمُ الْوَلِيدُ  

The Prophet ﷺ said: When one of you comes to an assembly, he should give a salutation and if he feels inclined to get up, he should give a salutation, for the former is not more of a duty than the latter. (Using translation from Abū Dāʾūd 5208)   

قَالَ رَسُولُ اللهِ ﷺ «إِذَا قَعَدَ أَحَدُكُمْ فَلْيُسَلِّمْ وَإِذَا قَامَ فَلْيُسَلِّمْ فَلَيْسَتِ الْأُولَى بِأَحَقَّ مِنَ الْآخِرَةِ»  

[Machine] Narrated Abu Hurairah: The Messenger of Allah ﷺ said, "When one of you enters a gathering, let him greet (the people). And when he intends to leave and the people are still sitting, let him greet them (again), for the former (greeting) is more deserving than the latter."  

حَدَّثَنَا أَبُو عَاصِمٍ النَّبِيلُ الضَّحَّاكُ بْنُ مَخْلَدٍ عَنْ يَزِيدَ بْنِ زُرَيْعٍ عَنْ رَوْحِ بْنِ الْقَاسِمِ عَنِ ابْنِ عَجْلَانَ عَنِ الْمَقْبُرِيِّ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللهِ ﷺ «إِذَا انْتَهَى أَحَدُكُمْ إِلَى الْمَجْلِسِ فَلْيُسَلِّمْ فَإِذَا أَرَادَ أَنْ يَقُومَ وَالْقَوْمُ جُلُوسٌ فَلْيُسَلِّمْ مَا الْأُولَى بِأَحَقَّ مِنْهَا»
