The people said, "O Messenger of Allah ﷺ! The rich people have got the highest degrees of prestige and the permanent pleasures (in this life and the life to come in the Hereafter)." He said, "How is that?" They said, "The rich pray as we pray, and strive in Allah's Cause as we do, and spend from their surplus wealth in charity, while we have no wealth (to spend likewise)." He said, "Shall I not tell you a thing, by doing which, you will catch up with those who are ahead of you and supersede those who will come after you; and nobody will be able to do such a good deed as you do except the one who does the same (deed as you do). That deed is to recite 'Subhan Allah ten times, and 'Al-Hamduli l-lah ten times, and 'AllahuAkbar' ten times after every prayer."  

عَنْ أَبِي هُرَيْرَةَ قَالُوا يَا رَسُولَ اللَّهِ ذَهَبَ أَهْلُ الدُّثُورِ بِالدَّرَجَاتِ وَالنَّعِيمِ الْمُقِيمِ قَالَ كَيْفَ ذَاكَ قَالَ صَلَّوْا كَمَا صَلَّيْنَا وَجَاهَدُوا كَمَا جَاهَدْنَا وَأَنْفَقُوا مِنْ فُضُولِ أَمْوَالِهِمْ وَلَيْسَتْ لَنَا أَمْوَالٌ قَالَ أَفَلاَ أُخْبِرُكُمْ بِأَمْرٍ تُدْرِكُونَ مَنْ كَانَ قَبْلَكُمْ وَتَسْبِقُونَ مَنْ جَاءَ بَعْدَكُمْ وَلاَ يَأْتِي أَحَدٌ بِمِثْلِ مَا جِئْتُمْ إِلاَّ مَنْ جَاءَ بِمِثْلِهِ تُسَبِّحُونَ فِي دُبُرِ كُلِّ صَلاَةٍ عَشْرًا وَتَحْمَدُونَ عَشْرًا وَتُكَبِّرُونَ عَشْرًا  

(the freed slave of Al-Mughira bin Shuʿba) Al-Mughira wrote to Muawiya bin Abu Sufyan that Messenger of Allah ﷺ used to say at the end of every prayer after the Taslim, "La ilaha illa-l-lahu wahdahu la sharika lahu; lahu-l-mulk wa lahu-l-hamd, wahuwa 'ala kulli shai'n qadir. Allahumma la mani'a Lima a taita, wa la mu'ta Lima mana'ta, wa la yanfa'u dhal-jaddu minkal-jadd.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُ فِي دُبُرِ كُلِّ صَلاَةٍ إِذَا سَلَّمَ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهْوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ اللَّهُمَّ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِيَ لِمَا مَنَعْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ وَقَالَ شُعْبَةُ عَنْ مَنْصُورٍ قَالَ سَمِعْتُ الْمُسَيَّبَ
