عَنْ أَبِي عَبْدِ الرَّحْمَنِ عَبْدِ اللَّهِ بْنِ عُمَرَ بْنِ الخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «بُنِيَ الإِسْلَامُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لَا إلَهَ إلَّا اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ، وَإِقَامِ الصَّلَاةِ، وَإِيتَاءِ الزَّكَاةِ، وَحَجِّ الْبَيْتِ، وَصَوْمِ رَمَضَانَ».
Kutoka kwa Abuu Abdirahman Abdallah bin Omari bin Khattwab radhi za Mweneyzi Mungu ziwe juu yake amesema: Nilimsikia Mtume rehema na amani ziwe juu yake: "Umejengwa uislamu kwa mambo matano: Kushuhudia kuwa hapana Mola apasaye kuabudiwa kwa haki isipokuwa Mwenyezi Mungu, nakuwa Muhammadi ni Mja wake na Mtume wake, na kusimamisha swala, na kutoa zaka, na kuhiji nyumba tukufu, na kufunga ramadhani".
Abu ‘Abdur-Rahmān ‘Abdullah ibn ‘Umar ibn al-Khattāb (may Allah be pleased with him) reported: I heard the Messenger of Allah (ﷺ) say: "Islam is built on five: testifying that there is no god but Allah and that Muhammad is His slave and Messenger, establishing prayer, giving Zakah, performing Hajj to the (Sacred) House, and fasting Ramadān."
