Shaykhul Islam Abul Abbas ibn Taymiyyah (rahimahullah) said:

 فمن قال : إن علم الله كعلمي أو قدرته كقدرتي أو كلامه مثل كلامي أو إرادته ومحبته ورضاه وغضبه مثل إرادتي ومحبتي ورضائي وغضبي أو استواءه على العرش كاستوائي أو نزوله كنزولي أو إتيانه كإتياني ونحو ذلك فهذا قد شبه الله ومثله بخلقه تعالى الله عما يقولون وهو ضال خبيث مبطل بل كافر 

And who would say:  Knowledge of Allah is like my knowledge, or power of Allah is like my power, or His speech is like my speech, or his will is like my will, or His love, Pleasure, Anger are like my love, pleasure, anger. Or his Istiwa on the Throne is like my Istiwa, or His descending is like my descending or His coming is like my coming. Or something like this, he would make tashbih of Allah and liken Him to His creation. Allah is away from what they say, and he (the one who would say such things) IS MISGUIDED, UGLY (HABITH), MUBTIL, AND KAFIR!
