The same chapter also discusses emergency delay:
• If a midwife fears that a child may die, she gives the necessary care priority. If already praying, the prayer is stopped; if the emergency exists before starting, the prayer may have to be delayed while the child is attended.
• A traveler who genuinely fears robbers or highway attackers is given an emergency allowance to delay the current prayer under the stated rule.
These are exceptional danger cases, not ordinary scheduling preferences.
