Hadith 6:43
Abu al-Ahwas narrated to us, from Abu Ishaq, from al-Harith, from Ali, who said: The Messenger of Allah (peace be upon him) said: "It is the duty of a Muslim towards a Muslim that he visits him when he is sick, and attends his funeral."
حدثنا أبو الآحوص عن أبي إسحاق عن الحارث عن علي قال قال رسول الله صلى الله عليه وسلم للمسلم على المسلم أن يعوده إذا مرض ويحضر جنازته
