What should I do when I am 19 years old and my mother prevents me from going to Fajr prayer in the mosque, knowing that the mosque is not very far?

If the questioner finds a congregation to perform Fajr prayer at home, obeying his mother takes precedence because, according to the majority of scholars, the reward for congregational prayer can be obtained outside the mosque.

However, if he does not find a congregation at home, he should strive to convince his mother to go to the mosque. If she is not convinced, then it is not permissible to obey her in staying away from congregational prayer, as it is obligatory for an able-bodied man, according to the preponderant opinion, unless there is an excuse.
