Bin Baz's AlFetawi, part 4 and 5 page 130 and 71:
Through explaining God's saying, (On that day, [a leg shall be revealed] and they shall be called upon to make obeisance, but they shall not be able. 68:42), the Prophet (peace be upon him) asserted that when the Lord shall come on Resurrection Day, He will show his leg to His believing servants. This is the sign between Him and them. Hence, as soon as they see His leg, they will recognize and follow him. This is one of Allah's unparalleled attributes fitting His glory and magnificence. The same is said about the other divine attributes proved by texts; such as hands, foot, eye and the like. The other attributes; such as ire, affection, abhorrence and the like, are involved in elevation and fitting Allah, the Glorified the Exalted, provided that they are indicated through the Glorious Book of Allah and the Prophet's traditions. Interpretation and evading resting upon the extrinsic meanings of aspects of such texts, is the sect of the heretic Jahmites and Mutazilites and their fellows. It is a defective sect denied and discharged by Sunnis who warned against people of such heretic factions.
This scholar hints at forbiddingness of opting for metaphor and metonymy of the expression 'leg', and insisting on referring to its extrinsic meaning. This means that Allah has a material leg such as that of any of Wahabists' scholars! Exalted be Allah against what they are imputing.
