Imam Al-Nawawi’s Riyad-us-Saliheen
Excellence of mixing with People and attending their social activities
Imam An-Nawawi says: Remember! Mixing with people in the way I have mentioned earlier is most desirable. This was the way of Messenger of Allah (sallallaahu alayhi wa sallam) and other Prophets of Allah, the Righteous Caliphs (May Allah be pleased with them), the followers of the Companions, scholars and pious people. The majority of the followers of the Companions and their followers adopted it. Imam Ash-Sha-fi`i, Imam Ahmad and the majority of other jurists followed it.
Allah, the Exalted, says:
“Help you one another in Al-Birr and At-Taqwa (virtue, righteousness and piety).” (5:2)
The Quranic Verses on the subject are many and well-known.
