When is mixing with people the stronger position, and when is seclusion obligatory?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is better, mixing with people or seclusion?

Answer:
The scholars have distinguished between the two. They said that if a person’s mixing with people brings benefits—such as benefiting them, calling them to Allah, teaching them, enjoining good, and forbidding evil—then he should mix with people. The Prophet (peace and blessings be upon him) used to visit the disbelievers in their gathering places and call them to Allah, reciting the Qur'an to them while they were disbelievers. However, if a person is unable to forbid evil, lacks the knowledge to clarify things to them and teach them, and has no capacity for it, then he should seclude himself. It is obligatory for him to seclude himself. Yes.
