None should make one'& brother stand and then sit at his place (and it was common with) Ibn Umar that when any person stood in the company (with a view to making room for him) he did not sit there.  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ يُقِيمَنَّ أَحَدُكُمْ أَخَاهُ ثُمَّ يَجْلِسُ فِي مَجْلِسِهِ وَكَانَ ابْنُ عُمَرَ إِذَا قَامَ لَهُ رَجُلٌ عَنْ مَجْلِسِهِ لَمْ يَجْلِسْ فِيهِ  

that the Messenger of Allah ﷺ said: "Let one of you not have his brother stand from his seat then sit in it."  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يُقِمْ أَحَدُكُمْ أَخَاهُ مِنْ مَجْلِسِهِ ثُمَّ يَجْلِسُ فِيهِ قَالَ وَكَانَ الرَّجُلُ يَقُومُ لاِبْنِ عُمَرَ فَلاَ يَجْلِسُ فِيهِ  

When anyone amongst you stands up, and in the badltb transmitted on the authority of Abu 'Awina, the words are:" He who stands in his place and (goes away) and then comes back to it, he his the greatest right (to occupy that).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قَامَ أَحَدُكُمْ وَفِي حَدِيثِ أَبِي عَوَانَةَ مَنْ قَامَ مِنْ مَجْلِسِهِ ثُمَّ رَجَعَ إِلَيْهِ فَهُوَ أَحَقُّ بِهِ  

When we came to the Prophet ﷺ, each one would sit down where there was room.  

كُنَّا إِذَا أَتَيْنَا النَّبِيَّ ﷺ جَلَسَ أَحَدُنَا حَيْثُ يَنْتَهِي  

The Prophet ﷺ said, "Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jumua prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutba, his sins in-between the present and the last Friday would be forgiven."  

قَالَ النَّبِيُّ ﷺ لاَ يَغْتَسِلُ رَجُلٌ يَوْمَ الْجُمُعَةِ وَيَتَطَهَّرُ مَا اسْتَطَاعَ مِنْ طُهْرٍ وَيَدَّهِنُ مِنْ دُهْنِهِ أَوْ يَمَسُّ مِنْ طِيبِ بَيْتِهِ ثُمَّ يَخْرُجُ فَلاَ يُفَرِّقُ بَيْنَ اثْنَيْنِ ثُمَّ يُصَلِّي مَا كُتِبَ لَهُ ثُمَّ يُنْصِتُ إِذَا تَكَلَّمَ الإِمَامُ إِلاَّ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الأُخْرَى  

Messenger of Allah ﷺ said, "Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اغْتَسَلَ يَوْمَ الْجُمُعَةِ وَتَطَهَّرَ بِمَا اسْتَطَاعَ مِنْ طُهْرٍ ثُمَّ ادَّهَنَ أَوْ مَسَّ مِنْ طِيبٍ ثُمَّ رَاحَ فَلَمْ يُفَرِّقْ بَيْنَ اثْنَيْنِ فَصَلَّى مَا كُتِبَ لَهُ ثُمَّ إِذَا خَرَجَ الإِمَامُ أَنْصَتَ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الأُخْرَى  

The Messenger of Allah ﷺ said: It is not lawful for a man to separate two persons except with their permission.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ لِرَجُلٍ أَنْ يُفَرِّقَ بَيْنَ اثْنَيْنِ إِلاَّ بِإِذْنِهِمَا  

I heard the Messenger of Allah ﷺ as saying: The best places to sit are those which provide most room. Abu Dawud said: The name of 'Abd al-Rahman b. Abi 'Amr is 'Abd al-Rahman b. 'Amr b. Abi 'Umrat al-Ansari.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ خَيْرُ الْمَجَالِسِ أَوْسَعُهَا  

The Messenger of Allah ﷺ said: “Whoever sits in a sitting and engages in much empty, meaningless speech and then says before getting from that sitting of his: ‘Glory is to You, O Allah, and praise, I bear witness that there is none worthy of worship except You, I seek You forgiveness, and I repent to You, (Subḥānaka Allāhumma wa biḥamdika, ashhadu an lā ilāha illā anta, astaghfiruka wa atūbu ilaik)’ whatever occurred in that sitting would be forgiven to him.”  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ جَلَسَ فِي مَجْلِسٍ فَكَثُرَ فِيهِ لَغَطُهُ فَقَالَ قَبْلَ أَنْ يَقُومَ مِنْ مَجْلِسِهِ ذَلِكَ سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ إِلاَّ غُفِرَ لَهُ مَا كَانَ فِي مَجْلِسِهِ ذَلِكَ وَفِي الْبَابِ عَنْ أَبِي بَرْزَةَ وَعَائِشَةَ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ صَحِيحٌ مِنْ هَذَا الْوَجْهِ لاَ نَعْرِفُهُ مِنْ حَدِيثِ سُهَيْلٍ إِلاَّ مِنْ هَذَا الْوَجْهِ  

When the Messenger of Allah ﷺ intended to get up from the assembly he used to say in the last. Glory be to Thee. O Allah, and I begin with praise of Thee, I testify that there is no god but Thou; I ask Thy pardon, and return to Thee in repentance. The man asked: Messenger of Allah! you utter the words now which you did not do in the past? He replied: (This is an) atonement for what takes place in the assembly.  

كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ بِأَخَرَةٍ إِذَا أَرَادَ أَنْ يَقُومَ مِنَ الْمَجْلِسِ سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ أَنْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ إِنَّكَ لَتَقُولُ قَوْلاً مَا كُنْتَ تَقُولُهُ فِيمَا مَضَى قَالَ كَفَّارَةٌ لِمَا يَكُونُ فِي الْمَجْلِسِ  

“Rarely would the Messenger of Allah ﷺ stand from a sitting until he supplicated with these words for his Companions: ‘O Allah, apportion for us, fear of You, that shall come between us and disobedience of You, and of obedience to You, which shall cause us to obtain Your Paradise, and of certainty, which shall make the afflictions of the world easy for us, and enjoyment of our hearing, and our seeing, and our strength as long as You keep us alive, and make it the inheritor of us. And let our vengeance be upon those who have wronged us, and aid us against those who show enmity towards us, and do not make our affliction in our religion, and do not make this world our greatest concern, nor the limit of our knowledge, and do not give power over us to those who will not have mercy on us. (Allāhumma-qsim lanā min khashyatika mā yaḥūlu, bainanā wa baina maʿāṣīka wa min ṭāʿatika mā tuballighuna bihī jannatak, wa minal-yaqīni mā tuhawwinu bihī ʿalainā muṣībatid-dunyā, wa mattiʿna bi-asmāʿinā wa abṣārina wa quwwatina mā aḥyaytanā, wajʿalhul-wāritha minnā, wajʿal tha’ranā ʿalā man ẓalamanā, wanṣurna ʿalā man ʿādānā, wa lā tajʿal muṣībatanā fī dīninā, wa lā tajʿalid-dunyā akbara hamminā wa lā mablagha ʿilminā, wa lā tusalliṭ ʿalainā man lā yarḥamunā).’”  

قَلَّمَا كَانَ رَسُولُ اللَّهِ ﷺ يَقُومُ مِنْ مَجْلِسٍ حَتَّى يَدْعُوَ بِهَؤُلاَءِ الْكَلِمَاتِ لأَصْحَابِهِ اللَّهُمَّ اقْسِمْ لَنَا مِنْ خَشْيَتِكَ مَا يَحُولُ بَيْنَنَا وَبَيْنَ مَعَاصِيكَ وَمِنْ طَاعَتِكَ مَا تُبَلِّغُنَا بِهِ جَنَّتَكَ وَمِنَ الْيَقِينِ مَا تُهَوِّنُ بِهِ عَلَيْنَا مُصِيبَاتِ الدُّنْيَا وَمَتِّعْنَا بِأَسْمَاعِنَا وَأَبْصَارِنَا وَقُوَّتِنَا مَا أَحْيَيْتَنَا وَاجْعَلْهُ الْوَارِثَ مِنَّا وَاجْعَلْ ثَأْرَنَا عَلَى مَنْ ظَلَمَنَا وَانْصُرْنَا عَلَى مَنْ عَادَانَا وَلاَ تَجْعَلْ مُصِيبَتَنَا فِي دِينِنَا وَلاَ تَجْعَلِ الدُّنْيَا أَكْبَرَ هَمِّنَا وَلاَ مَبْلَغَ عِلْمِنَا وَلاَ تُسَلِّطْ عَلَيْنَا مَنْ لاَ يَرْحَمُنَا  

The Prophet ﷺ said: People who get up from an assembly in which they did not remember Allah will be just as if they had got up from an ass's corpse, and it will be a cause of grief to them.  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ قَوْمٍ يَقُومُونَ مِنْ مَجْلِسٍ لاَ يَذْكُرُونَ اللَّهَ فِيهِ إِلاَّ قَامُوا عَنْ مِثْلِ جِيفَةِ حِمَارٍ وَكَانَ لَهُمْ حَسْرَةً  

the Prophet said: “No group gather in a sitting in which they do not remember Allah, nor sent Salat upon their Prophet, except it will be a source of remorse for them. If He wills, He will punish them, and if He wills, He will forgive them.”  

عَنِ النَّبِيِّ ﷺ قَالَ مَا جَلَسَ قَوْمٌ مَجْلِسًا لَمْ يَذْكُرُوا اللَّهَ فِيهِ وَلَمْ يُصَلُّوا عَلَى نَبِيِّهِمْ إِلاَّ كَانَ عَلَيْهِمْ تِرَةً فَإِنْ شَاءَ عَذَّبَهُمْ وَإِنْ شَاءَ غَفَرَ لَهُمْ  

The Prophet ﷺ said: If anyone lies on his side where he does not remember Allah, deprivation will descend on him on the Day of Resurrection; and if anyone sits in a place where he does not remember Allah, deprivation will descend on him on the Day of Resurrection.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اضْطَجَعَ مَضْجَعًا لَمْ يَذْكُرِ اللَّهَ تَعَالَى فِيهِ إِلاَّ كَانَ عَلَيْهِ تِرَةً يَوْمَ الْقِيَامَةِ وَمَنْ قَعَدَ مَقْعَدًا لَمْ يَذْكُرِ اللَّهَ ﷻ فِيهِ إِلاَّ كَانَ عَلَيْهِ تِرَةً يَوْمَ الْقِيَامَةِ
