Hadith 3
On the authority of Abdullah, the son of Umar ibn al-Khattab (ra), who said: I heard the Messenger of Allah (ﷺ) say, «Islam has been built on five pillars: testifying that there is no deity worthy of worship except Allah and that Muhammad is the Messenger of Allah, establishing the salah (prayer), paying the zakat (obligatory charity), making the hajj (pilgrimage) to the House, and fasting in Ramadhan.» – Bukhari & Muslim
