All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
You should know, dear brother, that it is not permissible for an adult sane Muslim male to fail to perform the Friday prayer without a sound reason, like sickness or travel. Studies are not a sound religious reason for abandoning the Friday prayer as clarified in Fatwa 85495, and it is not permissible to obey the parents in this regard. We have already clarified the sin and the threat of abandoning the Friday prayer in Fataawa 88869 and 91358, and we clarified in Fatwa 84942 that there is no obedience to a creature in disobeying the Creator; so please refer to the above Fataawa.
Therefore, we advise you to endeavour to convince your mother or father with the importance of attending the Friday prayer and the danger and threat of abandoning it. Additionally, you may show them the above-referred Fataawa. Moreover, you may seek the help of the pious and righteous people who know your parents and who may influence them.
Then, if your mother insists on her view, take your matter to the administration of the school and seize the advantage of the article of the law which states the freedom of belief in order to force them to allow you to go out to perform the Friday prayer. If this is not possible, then try to move to another school which does not necessitate the permission of the parents for going out of the school, and you should earnestly supplicate Allaah, as Allaah Says (what means): {And your Lord says, "Call upon Me; I will respond to you.}[Quran 40:60].
Your mother should fear Allaah and she should know that she will stand before Him, and it is only then that she will realize the evil fate of favoring studies over the Friday prayer. Moreover, she should know that she will be questioned by Allaah about the cultivation of her children, and she is required to protect her children from Hellfire. Allaah Says (what means): {O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones.}[Quran 66:6].
Ordering her children to abandon the Friday prayer is exposing them to the punishment in the Hereafter, so she should fear Allaah. On the contrary, she should be thankful and grateful to Allaah Who blessed her with a son who is keen on performing the prayer, despite living in a society that is overwhelmed by disbelief and dissoluteness. She should be the best helper for him in obeying Allaah and not an obstacle for him in doing so.
Allaah Knows best.
