Question : Is it wrong, O Shaykh, to rebuke someone who does not pray the greeting of the mosque after 'Asr?

Answer : It is not wrong to rebuke, because some scholars say it is not prescribed. Matters of scholarly disagreement are not subject to rebuke, but there is no harm in discussing it with him if he is capable of discussion. However, if he is one who follows a scholar without knowing his evidence, and you do not approve of his position, you are not more knowledgeable than so-and-so, so you cannot follow him. Yes.
