Ibn 'Umar (May Allah be pleased with them) reported:
The Messenger of Allah (ﷺ) said, "(The superstructure of) Islam is based on five (pillars), testifying the fact that La ilaha illallah wa anna Muhammad-ar-Rasul-ullah <b>[there is no true god except Allah, and Muhammad ((ﷺ)) is the Messenger of Allah]</b>, establishing As- Salat (the prayers), paying Zakat (poor due), the pilgrimage to the House <b>[of Allah (Ka'bah)]</b>, and the Saum (fasting) during the month of Ramadan." <b>[Al-Bukhari and Muslim]</b>.
وعن ابن عمر رضي الله عنهما أن رسول الله صلى الله عليه وسلم قال: بني الإسلام على خمس: شهادة أن لا إله إلى الله وأن محمدًا رسول الله، وإقام الصلاة، وإيتاء الزكاة، وحج البيت، وصوم رمضان" ((متفق عليه))
