Numerous factors can affect student learning outcomes in memorizing the Qur’ân. This study, therefore, aims to examine the effect of memorization background on students' learning outcomes of memorizing the Qur'ân, the effect of learning motivation on students' learning outcomes of memorizing the Qur'ân, the effect of self-efficacy on students' learning outcomes of memorizing the Qur'ân, the effect of Arabic language skills on students' learning outcomes of memorizing Al-Qur'ân, and simultaneously test the effect of the memorization background, learning motivation, self-efficacy, and Arabic language skills on students' learning outcomes of memorizing Al-Qur'ân. The research used a quantitative approach with a correlational type. The research population was all students in grades VII, VIII, and IX of MTs Yanbû' Al-Qur'ân Kudus, totaling 495 students. Meanwhile, using the proportionate stratified random sampling technique, the research sample of 120 students was obtained. The data were collected using a questionnaire, test, and documentation.
