Nafi' bin Yazid al-Kula'i نافع بن يزيد الكلاعي · General Behavior (Kitab Al-Adab)

The Prophet (ﷺ) said: Shall I not inform you of something more excellent in degree than fasting, prayer and almsgiving (sadaqah)? The people replied: Yes, Prophet of Allah! He said: It is putting things right between people, spoiling them is the shaver (destructive).

A man asked the Messenger of Allah (May peace be upon him): When aspect of Islam is best? He replied: that you should provide food and greet both those you know and those you do not know.
