قُمْ، اضْطَجِعْ حَتَّى الْمَسَاءِ
Stand up, then lie down until evening.
In the illustrative sequence “stand, then lie down until evening,” the first instruction seeks standing and the second seeks lying down for a specified period. Prompt execution gives the two actions an intelligible order; unrestricted deferral of the first may create a conflict in the listener’s understanding.
Thumma signals sequence with a delay, but the rhetorical issue is not merely the particle: it is the compatibility, timing and possible revision of successive directions. The duration of each act must be understood before declaring the orders contradictory.
