قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بُنِيَ الإِسْلاَمُ عَلَى خَمْسٍ شَهَادَةِ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَإِقَامِ الصَّلاَةِ، وَإِيتَاءِ الزَّكَاةِ، وَالْحَجِّ، وَصَوْمِ رَمَضَانَ ".
Ibn Umar reported: The Messenger of Allah ﷺ said: “Islam is built upon five: testifying that there is no god but Allah and that Muhammad is the Messenger of Allah, establishing the prayer, giving Zakat, Hajj, and fasting in Ramadan.”
