As-salaam alaikum. I just finished reading Musa Furber’s translation of Imam Al-Nawawi’s famous book “Etiquette With the Quran” and firmly recommend it to all Muslims to read as well. Imam Al-Nawawi was a scholar of the Shafi’i school and is well-known for his important scholarly works. He died in the year 676 AH. May Allah (Glorified and Exalted be He) reward him for his tireless efforts in propagating the teachings of Islam. Ameen.
