وَلَمْ يَأْكُلْ مِنْهَا هُوَ وَلَا غَيْرُهُ مِنَ الْأَغْنِيَاءِ.
Translation: Neither the owner nor other wealthy persons may eat from this failed voluntary offering.
Ordinary voluntary hady was earlier listed among offerings the owner may eat. This sentence concerns a special case: the voluntary offering fails on the journey and is slaughtered there.
Its meat is reserved for the poor; this is a specific exception, not a contradiction.
