37 - Khalaf b. Hishām narrated to us: Khālid b. ʿAbdullāh narrated to us, from Yazīd b. Abī Ziyād, from ʿAbdullāh b. al-Ḥārith, from Kaʿb, who said: "When God, Mighty and Majestic, looked at Paradise, He said: 'Glad tidings (Ṭūbā) to your inhabitants.' So it increases twofold until its inhabitants enter it."
