Kitaab At-Tawheed, Chapter: 38 Whoever Denies Any of the Names and Attributes of Allah
Allah , says:
" Thus We have sent you among a people [before whom] other peoples have passed away, in order that you might recite to them what We have revealed to you. But they reject [Allah,] the Most Gracious! Say: "He is my Rabb: There is none worthy of worship save He; in Him I have placed my trust and to Him I shall return" (Qur'an 13:30)
In this verse, Allah , Most Glorified, Most High, informs us that He has sent His Messenger, Muhammad 
to this Ummah to lead them from the darkness of ignorance and despair, into the light of guidance and certainty, just as He sent to the previous nations, Messengers with Revelation, and that it is the responsibility of the Messenger to impart to his people the Message that was revealed to him, even though the disbelievers may reject it and deny Allah's Divine Names Attributes. In addition, He must remain steadfast in broadcasting the message of Tawheed, firm in his dependence upon Allah in all matters, and that he must turn to his Rabb in repentance and for guidance in every important affair.

In Saheeh Bukhari, it is reported that `Ali (ra) said: "Speak to the people in a way they will understand. Would you like that Allah and His Messenger be denied?"
In this narration, the fourth Khaleefah, `Ali Ibn Abi Talib (ra) commands the people of knowledge to guide the people by speaking to them in a manner suited to their intellects in order that they may understand, and not to engage them in speech which is above their level of comprehension. This would include lengthy and involved explanations of Allah's Name and Attributes, for that might lead to misunderstanding, causing them to deny something from Allah's Book or the Sunnah of His Prophet , causing them to be destroyed without even knowing the reason.
