What is the way to overcome repeated failure in studies and life, and to deal with the whispers of Satan, in order to restore closeness to Allah?

A Muslim woman should not speak of failure when she has completed the memorization of Allah's Book, for Allah's enabling of obedience is the greatest success. She must adhere to Allah's Book and act upon it. She should also examine the tangible reasons for any perceived failure and address them, while focusing on the positives, as mastering the Quran is evidence of excellent capabilities. Furthermore, she must believe in divine decree (Qadar), and that whatever befell her was for a divine wisdom, and that her well-being is in Allah's hands. She should engage in beneficial knowledge and righteous deeds, for salvation from Allah's punishment is the true success.
