These are some of the basic guidelines Muslims follow in their knowledge of God:

1. Eliminate any anthropomorphism (human qualities) from their
conception of Allah. His attributes are not like human attributes,
despite similar labels or appellations.
2. Have unwavering faith in exactly what Allah and Prophet Muhammad
(peace be upon him) described Allah to be, no more, no less.
3. Eradicate any hope or desire of learning or knowing the modality of His names and attributes.
4. Believe totally in all the names and attributes of Allah; one cannot believe in some and disbelieve the others.
5. One cannot accept the names of Allah without their associated attributes, i.e. one cannot say He is Al-Hayy - 'The Living' and then say that He is without life.
6. Similarity in names (or meanings) does not imply similarity in
what is being described (referents). As a robotics arm differs from a
human arm, so the "hand" of Allah is nothing like a human hand, His
speech is nothing like human speech, etc.
7. Certain words are ambiguous or vague in their meanings, and thus
may be susceptible to misinterpretation. Only those meanings that are
in accordance with what is specified by Allah and His Prophet (peace be
upon him) are acceptable.
