[Machine] The Prophet ﷺ used to sit after prayer as much as he would say, "O Allah, You are the Peace, and from You is the Peace. Blessed are You, O Possessor of Majesty and Honor."  

مَا كَانَ النَّبِيُّ ﷺ يَجْلِسُ بَعْدَ الصَّلَاةِ إِلَّا قَدْرَ مَا يَقُولُ «اللَّهُمَّ أَنْتَ السَّلَامُ وَمِنْكَ السَّلَامُ تَبَارَكْتَ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ»  

“Allahumma Antas-Salam wa minkas-salam tabarakta ya Dhal-jalali wal- ikram” (O Allah, You are As-Salam and from You is all peace, Blessed are You O Possessor of majesty and honour).” (Using translation from Ibn Mājah 928)  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَرَادَ أَنْ يَنْصَرِفَ مِنْ صَلَاتِهِ اسْتَغْفَرَ ثَلَاثَ مَرَّاتٍ ثُمَّ قَالَ «اللَّهُمَّ أَنْتَ السَّلَامُ وَمِنْكَ السَّلَامُ تَبَارَكْتَ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ»  

"Al-Mughirah bin Shu'bah wrote to Mu'awiyah (Saying) that the Messenger of Allah ﷺ used to say following every prayer, after the taslim: 'La Ilaha Illallah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa 'ala kulli shay'in qadir. Allahumma la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd. (There is none worthy of worship except Allah ﷺ alone with no partner or associate. He is the Dominion and to Him be all praise, and He is able to do all things. O Allah, one can withhold what You have given and none can give what You have withheld, and no wealth or fortune can benefit anyone for from You comes all wealth and fortune.)' (Using translation from Nasāʾī 1342)  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلَاةٍ مَكْتُوبَةٍ «لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ اللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ وَلَا مُعْطِيَ لِمَا مَنَعْتَ وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ»
