«ثم للتراخي، لكنه عند أبي حنيفة رحمه الله يفيد التراخي في اللفظ والحكم»
Thumma indicates a delay in wording and, in relevant cases, legal effect.
The sequence “first act, then second” is not merely a stylistic ornament. In some legal formulations, placing the later ruling after the first may affect when it applies.
When several declarations follow one condition with thumma between them, the interpreter asks whether all remain suspended on the original condition or whether a later one has an independent effect. The placement of the condition, the person's legal status, and the applicable juristic rules matter.
