Hadith on Prayer: Glorify Allah 33 times after every prayer

Abu Huraira reported: The poor emigrants came to the Messenger of Allah, peace and blessings be upon him, and they said, “The wealthy have taken the highest degrees and blessed ranks.” The Prophet said, “How is that?” They said, “They pray as we pray, they fast as we fast, they give in charity and we do not have charity to give, they free slaves and we have none to free.” The Prophet said, “Shall I teach you something by which you will reach those ahead of you, surpass those after you, and by which no one will be better than you but one who does like you?” They said, “Of course, O Messenger of Allah.” The Prophet said, “Glorify and exalt and praise Allah thirty three times after every prayer.”

عَنْ أَبِي هُرَيْرَةَ أَنَّ فُقَرَاءَ الْمُهَاجِرِينَ أَتَوْا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالُوا ذَهَبَ أَهْلُ الدُّثُورِ بِالدَّرَجَاتِ الْعُلَى وَالنَّعِيمِ الْمُقِيمِ فَقَالَ وَمَا ذَاكَ قَالُوا يُصَلُّونَ كَمَا نُصَلِّي وَيَصُومُونَ كَمَا نَصُومُ وَيَتَصَدَّقُونَ وَلَا نَتَصَدَّقُ وَيُعْتِقُونَ وَلَا نُعْتِقُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَفَلَا أُعَلِّمُكُمْ شَيْئًا تُدْرِكُونَ بِهِ مَنْ سَبَقَكُمْ وَتَسْبِقُونَ بِهِ مَنْ بَعْدَكُمْ وَلَا يَكُونُ أَحَدٌ أَفْضَلَ مِنْكُمْ إِلَّا مَنْ صَنَعَ مِثْلَ مَا صَنَعْتُمْ قَالُوا بَلَى يَا رَسُولَ اللَّهِ قَالَ تُسَبِّحُونَ وَتُكَبِّرُونَ وَتَحْمَدُونَ دُبُرَ كُلِّ صَلَاةٍ ثَلَاثًا وَثَلَاثِينَ مَرَّةً
