Easy

Islam, as derived from the Qur’an, has been made easy to understand so there should never be a need for exhaustive or complex explanations.

Al-Qamar 54:17 And We have indeed made the Qur’an easy to understand and remember: then is there any that will receive admonition?
 
Arabic: وَلَقَدْ يَسَّرْنَا الْقُرْآنَ لِلذِّكْرِ فَهَلْ مِن مُّدَّكِرٍ
