Mujammi' bin Yahya bin Harithah relates: I heard my paternal uncle Khalid bin Zayd al-Ansari (may Allah be pleased with him) say that the Messenger of Allah (peace and blessings be upon him) said: "Whoever pays the zakah, honours the guest, and gives (to help people) in times of calamity is free from miserliness."
