Wa-lā taʾti amran is a prohibition; idhā mā ishtabah supplies the crucial limiting circumstance. The advice concerns acting prematurely where a matter remains doubtful.
The preceding mirage image distinguishes visible attraction from actual benefit. The instruction makes that distinction practical: do not mistake appearance for a secure basis to act. It is not a blanket command never to make decisions.
Practice: Specify the scope: an unexamined action while relevant facts remain uncertain.
