(Imām Bukhārī narrates): Abul Yaman narrated the hadith to us, he said: Shu'aib informed us, from az-Zuhri, he said: Salim informed me, from Hazrat Abdullah bin Umar (Allāh be pleased with them both), he narrated that

I saw the Messenger of Allāh ﷺ, when he ﷺ had to depart quickly on a journey, he ﷺ would delay the Maghrib, until he ﷺ would combine and offer the Maghrib and Isha together.

Salim said: And when Hazrat Abdullah (Allāh be pleased with him) had to depart quickly on a journey, he also used to do the same.
