How can one help a newlywed woman who started wearing the hijab immediately after marriage, and was religiously committed before it, but now finds herself distant from prayer, acts of worship, and religious gatherings, and feels tired and sad due to her lack of devotion and unwillingness to read the Qur’an, so that she may return close to her religion, her Lord, and her Qur’an?

What you feel of weakness and deficiency in faith is from the creed of Ahl al-Sunnah wal-Jama'ah, as faith increases and decreases. This may be due to a sin or an innovation, for Allah punishes the disobedient by forsaking good deeds and depriving them of their sweetness, as it was said: "Your sins have shackled you." Therefore, you must repent to Allah from all sins, especially major sins such as disobeying parents, consuming unlawful earnings, and listening to music, and increase in seeking forgiveness and supplicating to Allah.
