The Ruling on Marrying a Daughter to a Man Who Does Not Pray

His final question states: What is the ruling on a man who marries his sister or his daughter to a man who does not pray, while he knows this, but due to circumstances, this marriage took place, including the kinship ties and pressure from relatives? Does his guardian sin?
Answer: One who does not pray is not permissible to marry a Muslim woman; because abandoning prayer is disbelief, we seek refuge in Allah. So, one who does not pray is not permissible to marry, and you were wrong in this marriage and you have sinned. You bear a great sin in marrying your daughter to a man who does not pray. This is not permissible. The correct view according to the reliable scholars of knowledge is that abandoning prayer is major shirk (associating partners with Allah) that expels one from the religion; due to the saying of the Prophet (peace and blessings be upon him): , and in other hadiths that indicate this.
So, it is obligatory for you to strive for the separation between her and him, unless he repents. If he repents to Allah, returns, and becomes upright in prayer, then there is no harm. Otherwise, it is obligatory for you, just as you brought her into this affliction, to strive to remove her and separate her from him; because this is what is obligatory for you. It is not permissible for her to marry a disbeliever who does not pray, and it is not permissible for you to enable her to do so, even if the relatives pressured you. The right of Allah is greater, and the ruling of Allah is more deserving of consideration.
So, the result is that you must remove her from this affliction just as you brought her into it, and you must strive to separate them, unless he repents. And if he repents, there is no harm in her remaining with him. And whoever repents, Allah accepts his repentance. May Allah grant all of you guidance, righteousness, and well-being from all evil. Yes.
