عَنْ عَبْدِ اللهِ بنِ عُمَر رضي الله عنهما قال: قال رسولُ الله صلى الله عليه وسلم: «بُنِيَ الْإِسْلَامُ عَلَى خَمْسٍ: شَهَادَةِ أَنْ لَا إِلَهَ إِلَّا اللهُ، وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ، وَإِقَامِ الصَّلَاةِ، وَإِيتَاءِ الزَّكَاةِ، وَحَجِّ الْبَيْتِ، وَصَوْمِ رَمَضَانَ».
kutoka kwa Abdullahi bin Amry -Radhi za Mwenyezi Mungu ziwe juu yao- amesema: Amesema Mtume wa Mwenyezi Mungu -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".
‘Abdullah ibn ‘Umar (may Allah be pleased with him and his father) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "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."
