Some Ash'aris like Ibn Khafif attribute a Yad to Allah. He says in al-Aqida al-Sahiha:
I agree that they did not intend by it the literal meaning in the sense of limb that comes first to mind.
But, if some word is mentioned mudaaf to Allah it is not necessarily an attribute and the reason we know this is because of its meaning. Like the case of Naaqat Allah which we say is not an attribute of Allah.
Now bearing that in mind, I presume one can only Attribute a Yad to Allah, if he knows what Yad means. If one does not know what Yad means, then how could he say it is an attribute of Allah, for Yad Allah could easily be the second type of mudaf, like Kab'at Allah?

He says that Adam's rank is signified as special by having this statement referring to him in the Quran, even if it, strictly speaking, holds true for other creations as well.
