Jumuah Khutbah regarding how to properly understand and act upon the five pillars of Islam:

عَنْ أَبِي عَبْدِ الرَّحْمَنِ عَبْدِ اللَّهِ بْنِ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: سَمِعْت رَسُولَ اللَّهِ صلى الله عليه و سلم يَقُولُ: " بُنِيَ الْإِسْلَامُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لَا إلَهَ إلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَإِقَامِ الصَّلَاةِ، وَإِيتَاءِ الزَّكَاةِ، وَحَجِّ الْبَيْتِ، وَصَوْمِ رَمَضَانَ".
[رَوَاهُ الْبُخَارِيُّ]
، [وَمُسْلِمٌ].

On the authority of Abdullah, the son of Umar ibn al-Khattab (radyallaahu anhumaa), who said:

I heard the Messenger of Allah (ﷺ) say, "Islam has been built on five [pillars]: testifying that there is no deity worthy of worship except Allah and that Muhammad is the Messenger of Allah, establishing the salah (prayer), paying the zakat (obligatory charity), making the hajj (pilgrimage) to the House, and fasting in Ramadhan." [Bukhari & Muslim]
