وَلَهُ الْإِجَازَةُ إِذَا كَانَ الْمَعْقُودُ عَلَيْهِ بَاقِيًا وَالْمُتَعَاقِدَانِ بِحَالِهِمَا
Translation: The owner can ratify the transaction if the object of sale remains and the contracting parties remain in their legally relevant original status.
Quduri specifies two conditions for ratification:
1. The contracted subject matter still exists.
2. The two contracting parties remain in the relevant continuing legal position.
This is not a blanket rule that subsequent permission always cures every unauthorized sale.
Loss of the goods or a legally material change in the parties requires more detailed treatment.
