Is it permissible to reject suitors for the purpose of completing the memorization of the Quran and seeking obligatory knowledge, fearing that the suitor may not be pious enough to assist in this or may distract from commitment?

Initiating marriage is legally مطلوب (desirable), especially for young people, based on the Prophet's (peace be upon him) saying: "O young people, whoever among you can afford to marry, let him do so, for it helps him lower his gaze and guard his chastity. And whoever cannot afford it, let him fast, for it will be a shield for him." Marriage does not hinder the pursuit of knowledge; rather, it can assist in it and remove distracting thoughts. One must choose a righteous spouse who will aid in obeying Allah. The essential amount of knowledge does not consume much time and can be acquired after marriage. Therefore, it is advisable to accept marriage from someone whose religiosity and character you approve of.
