"Bring forward all the arguments you wish and say whatever you please and speak your mind freely. Now that you are safe and free to say whatever you please appoint some arbitrator who will impartially judge between us and lean only towards the truth and be free from the empery of passion, and that arbitrator shall be Reason, whereby God makes us responsible for our own rewards and punishments. Herein I have dealt justly with you and have given you full security and am ready to accept whatever decision Reason may give for me or against me. For "There is no compulsion in religion" (Qur'an 2:256) and I have only invited you to accept our faith willingly and of your own accord and have pointed out the hideousness of your present belief. Peace be with you and the blessings of God!"
According to George Makdisi and Hugh Goddard, "the idea of academic freedom" in universities was "modelled on Islamic custom" as practiced in the medieval Madrasah system from the 9th century.

Main article: Peace in Islamic philosophy
As in other Abrahamic religions, peace is a basic concept of Islam. The Arabic term "Islam" itself (إسلام) is usually translated as "submission"; submission of desires to the will of God. It comes from the term aslama, which means "to surrender" or "resign oneself".[80] The Arabic word salaam (سلام) ("peace") has the same root as the word Islam[81]. One Islamic interpretation is that individual personal peace is attained by utterly submitting to Allah. The greeting "As-Salamu Alaykum", favoured by Muslims, has the literal meaning "Peace be with you"[82]. Muhammad is reported to have said once, "Mankind are the dependents, or family of God, and the most beloved of them to God are those who are the most excellent to His dependents." "Not one of you believes until he loves for his brother what he loves for himself." Great Muslim scholars of prophetic tradition such as Ibn Hajar al-Asqalani and Yahya ibn Sharaf al-Nawawi have said
The major juristic schools of Islam have traditionally accepted the institution of slavery. However, Islam has prescribed five ways to free slaves, has severely chastised those who enslave free people, and regulated the slave trade. The source of slaves was restricted to war in preference to killing whole tribes en masse, as was the tradition at the time. Slaves also had more rights under Islam as an owner could not mistreat them. Many slaves were freed after certain period of time, if they accepted to convert to Islam, or if they were ransomed.
