question #2 Sahih Muslim 703b, Book 6, Hadith 53 : Under what circumstances did the Prophet Muhammad (ﷺ) combine the sunset and ‘Isha’ prayers?

Nafi’ reported that when Ibn ‘Umar was in a state of hurry on a journey, he combined the sunset and ‘Isha’ prayers after the twilight had disappeared, and he would say that when the Messenger of Allah (ﷺ) was in a state of hurry on a journey, he combined the sunset and ‘Isha’ prayers.
