The Wahhabi fatwa states:
والخلاصة في الردّ على ما ذكره صاحبك : أنّ سؤال الميت شرك ، وسؤال الحيّ ما لايقدر عليه إلا الله شرك أيضا والله أعلم .
الإسلام سؤال وجواب
الشيخ محمد صالح المنجد
To sum up our response to what your friend mentioned: asking the dead for anything is shirk, and asking the living for anything that no one except Allaah is able to do, is also shirk. And Allaah knows best.
Sheikh Muhammed Salih Al-Munajjid
While the Qur’an[43:45] says:
Sahih International: And ask those We sent before you of Our messengers; have We made besides the Most Merciful deities to be worshipped?
Muhsin Khan: And ask (O Muhammad SAW) those of Our Messengers whom We sent before you: “Did We ever appoint aliha (gods) to be worshipped besides the Most Beneficent (Allah)?”
Pickthall: And ask those of Our messengers whom We sent before thee: Did We ever appoint gods to be worshipped beside the Beneficent?
Yusuf Ali: And question thou our messengers whom We sent before thee; did We appoint any deities other than (Allah) Most Gracious, to be worshipped?
As per the standards of the Wahhabi fatwa, the Qur’an in this above verse is telling the Prophet(peace and blessings be upon him) to commit shirk, because it says to ask those Messengers who came before i.e., dead and passed away.
Now, the literalists are forced to accept this interpretation. If they are to add to it, more than its literal meaning, to explain it away, their literalist foundations would become void. And when their foundations are void, all of their other narrow literalist interpretations they made of the Qur’anic verses, in order to conclude the fatwa that “asking the dead is shirk“, would become void, nullifying the basis of their argumentation. So the Wahhabi is caught between a rock and a hard place.
Also note, according to the tafsirs, one of the accepted interpretations of this verse is that, this verse was revealed during the Isra where 70 of the Prophets were gathered. So even from this acceptable meaning, it is proven that our Master Muhammed (peace and blessings be upon him) did ask the Messengers who passed away. This is a Quranic refutation of Wahhabism and their claim that there is no such proof the Prophet(peace be upon him) ever asked anyone of those who passed away.
