(such as Abu Hanifa, al-Humaydî, Ibn Abî 'Âsim, Abû Dâwûd, and Abû Nasr al-Marwazî) reportedly used the term "the sunnah" narrowly to refer to Sunni Doctrine as opposed to the creeds of Shia and other non-Sunni Islamic sects. Sunnah literally means face, nature, lifestyle, etc. In the time of Muhammad's companion, newly converted Muslims accepted and rejected some set of creed by using reason. So many early Muslim scholars started writing books on creed entitled as 'sunnah'. In the Quran The word "sunna" appears several times in the Qur’an, but there is no specific mention of sunnah of the messenger or prophet (sunnat al-rasool, sunnat al-nabi or sunna al-nabawiyyah), i.e. the way/practice of Muhammad (there are several verses calling on Muslims to obey Muhammad—see below). Four verses (8.38, 15.13, 18.55) use the expression “sunnat al-awwalin”, which is thought to mean "the way or practice of the ancients". It is described as something "that has passed away" or prevented unbelievers from accepting God. “Sunnat Allah” (the "way of God") appears eight times in five verses. In addition, verse 17.77 talks of both the way of other, earlier Muslim messengers (Ibrahim, Musa, etc.), and of "our way", i.e. God's way. [This is] the way (sunna) of those whom we sent [as messengers] before you, and you will not find any change in Our way (sunnatuna). This indicates to some scholars (such as Javed Ahmad Ghamidi) that sunnah predates both the Quran and Muhammad, and is actually the tradition of the prophets of God, specifically the tradition of Abraham. Christians, Jews and the Arab descendants of Ishmael, the Arabized Arabs or Ishmaelites, when Muhammad reinstituted this practice as an integral part of Islam. History/etymology Prior to the "golden age of classical Islamic jurisprudence", the "ancient schools" of law prevailed. The tradition which not directly sourced from Hadith or practice of Muhammad and instead traced to solely some Sahabah were also acknowledged as one of the source of jurisprudence, as it was regarded by scholars of Islam such as Nawawi as "unrecorded Hadith" which not explicitly attributed to Muhammad himself but clearly practiced by the first generation of Muhammad's follower. Al-Nawawi has listed Zubayr ibn al-Awwam ruling regarding ethics of sitting down during eat and drinks in his book, Riyadh as Shaliheen, by basing the ethic in az-Zubayr practice, which narrated by his son, Abdulah. another manners and ethic ruling based on az-Zubayr covering
