Masha'allah
Definition
Masha'allah was an early medieval astrologer and astronomer represented through the collected Works of Sahl and Masha'allah.
Life and context
The collection places his work in the Arabic and Persian transmission that joined astronomical models, world astrology, questions, and electional practice.
Work and ideas
The reviewed collection supports source-specific context for ingress roots, questions, reception, perfection, phasis, and related timing or interference doctrines.
Scope and limitations
Because the registered source is shared with Sahl ibn Bishr, individual claims remain attributed at the passage level rather than assigned by proximity.

A slower collector receives two applying lights and gathers them into one perfected relation under the medieval collection doctrine.
A third party perfects first and blocks the intended matter, preserving Sahl's broader prohibition family and its cutting-off subtype.
A faster intermediary body separates from one significator and applies to another, carrying the light onward in the medieval transfer-of-light doctrine.
