How can a Muslim woman solve the problem of not having khushu' (devotional humility) in prayer and Satan making her doubt her wudu' (ablution)?

A Muslim's feeling of distress due to lack of khushu' (devotion/humility) in prayer is a good sign. To attain khushu', a Muslim must know that khushu' is the essence of prayer, and without it, prayer is like a dead body without a soul. Khushu' is also one of the greatest causes of success in this world and the hereafter, as Allah Almighty says: ﴿Successful indeed are the believers, those who humble themselves in their prayers.﴾ Khushu' is achieved by a servant turning to their prayer and turning away from worldly matters, and by striving to perform prayer in the manner of the Prophet, peace be upon him, along with contemplating the dhikr (remembrances) and pondering the meanings of the verses. Also, praying in plain clothes, in a place free of images, and away from noise contributes to khushu'. As for whispers (waswas), they are repelled by ignoring them and not paying attention to them. If Satan confuses the worshiper in their prayer, they should spit to their left three times and seek refuge with Allah from the accursed Satan.
