Notes (Tafseer)

5752. Ahata: surrounds, encompasses, encloses, guards on all sides, keeps under his own possession and control, and does not allow to be corrupted or debased. See last note but one.

5753. In the spiritual Kingdom,-as indeed, in all things,-Allah's knowledge, wisdom, and Plan comprehend all things, great and small. There is nothing which we do, nothing which happens that is outside His account.
