(4) باب وُجُوبِ عِيَادَةِ الْمَرِيضِ
Narrated Al-Bara bin Azib:
Allah's Messenger (ﷺ) ordered us to do seven things and forbade us to do seven other things. He forbade us to wear gold rings, silk, Dibaj, Istabriq, Qissy, and Maithara; and ordered us to accompany funeral processions, visit the sick and greet everybody. (See Hadith No. 104)
