There is a brother who teaches arabic in the mosque and he is seen in the eyes of people as a good and rightious muslim, but he repeatedly falls in major sins and fears hypocrisy of what the people think of him and of his reality. He asks if he should stop giving the lessons and focus on his emaan?

Ustadh AbdulAziz al-Haqqan

Let him do both and let this be a driving force for him to stop.
