We Must Know! (i.e. Learn)
A person must know how to act, how to speak, how to write, how to give Daʾwah (propagate the call of Islām), how to spread this Daʾwah (the call to Islām and Sunnah as the Ṣaḥābah understood them), how to confront opponents and in what manner (one should do so). Such as wisdom, patience, kindness, and others. The fundamental methodology in this Daʾwah (i.e. The Daʾwah of Salafiyyah) is wisdom, good preaching, and debate in a way that is best when engaging (with others) from the beginning.
