The Nawawi Forty is a text of forty-two noble prophetic hadiths collected by Yahya bin Sharaf al-Nawawi, known as Imam al-Nawawi, in the book The Forty in the Buildings of Islam and the Rules of Rulings, known as the Nawawi Forty.

Imam Al-Nawawi made a commitment in Al-Nawawi’s Forty that it be authentic, and he deleted its chains of transmission to make it easier to memorize, then he followed it with a chapter on controlling its hidden wording.

Imam al-Nawawi explained the reason for his plural of forty, saying:
“Among the scholars who collected the forty were in the fundamentals of religion, some in the branches, some in jihad, some in asceticism, and some in sermons, all of which are good goals, may God be pleased with those who seek them. I have seen the collection of forty more important than all of this, and they are forty hadiths that include all of that, and each hadith is a great rule of the religion, and scholars have described it as the orbit of Islam, or half of Islam, or a third of it, or something like that.
The forty and forty hadiths appeared based on a weak hadith that says: “Whoever preserves forty hadiths for my nation regarding matters of its religion, God Almighty will raise him on the Day of Resurrection to the group of jurists and scholars.”

Imam Al-Nawawi also said in the introduction to his book about this hadith and the extent of his reliance on it in collecting the forty nuclear: “The scholars have agreed that it is permissible to act on the weak hadith regarding the virtues of deeds, and despite this, my reliance is not on this hadith, but rather on his statement - may God’s prayers and peace be upon him - in the hadiths. The correct one is: “Let the witness among you inform the absent one,” and his saying: “May God bless someone who heard my statement and understood it, and performed it as he heard it.” Professor Maher al-Hindi commented on Al-Nawawi’s saying that relying on weak hadiths regarding the virtues of deeds is the opinion of the majority and is not agreed upon.

The author of the Forty Nawawi, Imam al-Nawawi:
He is Abu Zakaria Yahya bin Sharaf Al-Hazami Al-Nawawi Al-Shafi’i (631 AH - 1233 AD / 676 AH - 1277 AD), known as “Al-Nawawi.” He is a Muslim hadith scholar, jurist, and linguist, and one of the most prominent Shafi’i jurists. He is famous for his many books and classifications in jurisprudence, hadith, language, and biographies, such as Riyadh Al-Salihin, Al-Nawawi’s Forty, and Minhaj Al-Talibeen. And Al-Rawdha, and he is described as the editor of the Shafi’i school of thought, its refiner, its reviewer and its arranger, as the work was settled among the Shafi’i jurists according to what Al-Nawawi suggests. Al-Nawawi is called the Sheikh of the Shafi’is. If the word “two sheikhs” is used according to the Shafi’is, they mean Al-Nawawi and Abu Al-Qasim Al-Rafi’i Al-Qazwini.

Al-Nawawi was born in Nawa in the year 631 AH, and when he reached ten years of age, his father put him in a shop, so he did not preoccupy himself with buying and selling rather than learning and memorizing the Holy Qur’an, until he completed the Qur’an when he was close to puberty. He stayed in his hometown of Nawa until he reached eighteen years of age, then he moved to Damascus. Al-Nawawi came to Damascus in the year 649 AH, and he stayed with the Mufti of the Levant, Abd al-Rahman bin Ibrahim al-Fazari, and learned from him. Al-Nawawi remained in Damascus for about twenty-eight years, all of which he spent in a small house in the Al-Rawahiyah School, learning, teaching, and writing books. He assumed the presidency of Dar al-Hadith al-Ashrafiyya, until he passed away. Al-Minya in the year 676 AH.
