In refuting the abrogation claim of 5:5/2:221
which he rejects, Abu-Abdillah Shu`la, in his book صفوة الراسخ في علم المنسوخ والناسخ, page 114, asks the logical question "How can the former abrogate the latter?"
He asked that question to refute the claims made my some scholars that the abrogation case is the reverse; that it was 5:5 that was abrogated.
The verifier of his book, Dr. m. Ibrahim Faaris, agrees and quotes An-Nahhaas asking the same question.
Yet, Shu`la approves of the abrogation claim of 2:234/2:240
and does not comment on the abrogation claim of 33:50/33:52
. He must have been aware of this inconsistency though, because he claimed that 2:240 was revealed before 2:234, but he did not offer any evidence to back that up.
