Is it permissible for a Muslim to take a brother to assist him in obedience, such as maintaining the first row in prayer, or persevering in listening to a portion of the Quran, through mutual questioning and follow-up between them?

A Muslim's inquiry about the well-being of his Muslim brother in matters of both his faith and worldly affairs is considered a sign of true brotherhood and cooperation in righteousness and piety. This includes enjoining truth, such as waking someone for Fajr prayer, reminding them about lessons, and visiting the sick.

However, this inquiry and enjoining should be far from delving into the specifics of acts of worship, as this may lead to corruptions, such as a Muslim falling into lying, showing off, or conceit, or transforming hidden deeds into public ones.

If a Muslim sees his brother falling short in a particular act, he may advise and remind him specifically about it, without this becoming a permanent habit for every action.
