Arba'un 3 — Islam is built on five

الأربعون 3 — بني الإسلام على خمس

Abdullah ibn Umar's hadith on the pillars of Islam, the third hadith of al-Nawawi's Forty and of Ibn Rajab's commentary; transmitted by al-Bukhari (8) and Muslim (16) through Ikrama ibn Khalid, Sa'd ibn Ubayd and Muhammad ibn Zayd from Ibn Umar, and also by Ahmad (2/143), al-Tirmidhi (2609), al-Nasa'i, Ibn Khuzayma, Ibn Hibban and others; a version from Jarir ibn Abdullah al-Bajali is transmitted by Ahmad (4/363–364). Ibn Rajab explains Islam as a structure resting on these five supports, with belief in God and His Messenger included within islam (Jami' al-Ulum wal-Hikam pp. 121–130).
