What are the books or methods a Muslim can utilize to learn about the virtues of deeds in cases of conflicting interests or harms, so that they can deal with perplexing situations in these times?

Among the books that addressed these issues are: "Qawa'id al-Ahkam" by Al-Izz ibn Abd al-Salam, "Maqasid al-Shari'ah" by Ibn Ashour, "Al-Mukhtasar al-Wajiz fi Maqasid al-Tashri'" by Dr. Awad al-Qarni, and "Al-Mufadalah bayna al-Ibadat: Qawa'id wa Tatbiqat" by Sulaiman bin Muhammad al-Najran.
