حَدَّثَنَا هَاشِمٌ حَدَّثَنَا عَاصِمٌ عَنْ أَبِيهِ عَنْ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ بُنِيَ الْإِسْلَامُ عَلَى خَمْسٍ شَهَادَةِ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ وَإِقَامِ الصَّلَاةِ وَإِيتَاءِ الزَّكَاةِ وَحَجِّ الْبَيْتِ وَصَوْمِ رَمَضَانَ
مسند امام احمد بن حنبل · Hadith 6015
It was narrated from Ibn 'Umar that the Prophet (PBUH) said: "Islam is built upon five [pillars]: the testimony that there is no god but Allah and that Muhammad is the Messenger of Allah; establishing regular prayer (salaah); paying zakaah; Hajj (pilgrimage) to the House; and fasting Ramadaan."
