Ibn Daqiq al-'Id
Ibn Daqiq al-'Id, born in Yanbu into the Arab tribe of Banu Qushayr. He is accounted as one of Islam's great scholars in the fundamentals of Islamic law and belief, and was an authority in the Shafi'i legal school. Although Ibn Daqiq al-'Id studied Shafi'i jurisprudence under Ibn 'Abd al-Salam, he was also proficient in Maliki fiqh. He served as chief qadi of the Shafi'i school in Egypt. Ibn Daqiq al-'Id taught hadith to al-Dhahabi, al-Nuwayri, and other leading scholars of the next generation. In his lifetime, Ibn-Daqiq wrote many books but his commentary on the Nawawi Forty Hadiths has become his most popular. In it he comments on the forty hadiths compiled by Yahya Al-Nawawi and known as the al-Nawawi's Forty Hadith. His commentary has become so popular that it is virtually impossible for any scholar to write a serious book about the forty hadiths without quoting Ibn-Daqiq.
