What are the best supplications (adhkar) and deeds that relieve distress and elevate ranks, which one can diligently observe during the period of awaiting academic results, and what books contain these supplications and stories of relief?

The book "Kitab al-Adhkar" by Imam al-Nawawi is one of the most comprehensive books of prophetic supplications (adhkar). It contains chapters such as: "Supplication for Distress and Supplication for Important Matters" and "What to Say When Afflicted by Worry or Sadness," in addition to other chapters related to times of hardship and infirmities. There have been previous fatwas (religious edicts) that addressed means of alleviating distress, warding off misfortune, and matters that aid in the acceptance of supplication. As for books that mention stories of those whose prayers were answered, they are: "Mujabū al-Daʿwah" (Those Whose Prayers Were Answered) and "Al-Faraj baʿda al-Shiddah" (Relief After Hardship), both by Al-Hafiz Abu Bakr Ibn Abi al-Dunya, and the book "Al-Faraj baʿda al-Shiddah" by Al-Qadi al-Tanukhi.
