I came upon a card that has the name of Allah written all over it as well as some of His attributes. The problem is, they are in the form of a circular diagram as you find in amulets and some ta'weez. There is also a Shi'a du'a on it as well as the Shi'a kalimah on it (i.e. the addition of علي ولي الله at the end of the kalimah). On the flip side, there is a long du'a called "du'a e noor" that is hard to read, but from what I can decipher, it seems to be this du'a (warning: Shi'a website).
Is it permissible to directly dispose of the card or should it be buried? There is no ayah from the Qur'an on it but there are the names of Allah on it and besides the amulet-style diagrams, the entire back is full of the du'a mentioned before which also doesn't contain any Qur'anic verse. Also, I have never heard of this du'a before as it may not be sunnah and be derived from amongst the Shi'a but it doesn't appear to contain anything questionable, either.
