The Prophet ﷺ said, "Returning from a military expedition carries the same reward as the expedition itself."
عن النبي ﷺ قال: قفلة كغزوة.

Narrated by Abu Dawud (2487), Ahmad (6625), Hakim (2/73), and Bayhaqi (9/28) through various routes from Layth bin Saad, who said, Haywa bin Shurayh narrated to me, from Ibn Shufay Asbahi, from his father Shufay bin Matie, from Abdullah bin Amr, and he related it. Except that in Mustadrak "from his father" is not mentioned. Abu Dawud (2487) narrated it from the same route as Hakim's, mentioning "from his father," so it appears this phrase was dropped by the copyists, which is why Ibn Hajar did not mention it in Ithaf Mahra (9/672). Its chain of transmission is sahih, and Ibn Shufay is Husayn.Hakim said, sahih according to the criteria of Muslim. I say, Muslim did not narrate for Husayn bin Shufay, nor for his father, though both are trustworthy.Khattabi said in Maalim Sunan (3/358), commenting on the aforementioned hadith, "This can be understood in two ways. The first is that he meant by it the return from a military expedition and going back home, meaning that the reward of the one waging jihad in his return to his family is like his reward in setting out for jihad. This is because equipping oneself for a raid burdens one's family, and in one's return to them there is a removal of that burden, a rest for the soul, and a renewal of strength for a future expedition.The other way is that he meant by it a repeated return, meaning going back a second time along the same path by which one had withdrawn, even if one had not encountered the enemy or witnessed battle. An army sometimes does this when withdrawing from its expedition, for one of two reasons. The first is that when the enemy sees them withdrawing from their territory, they feel secure and come out from their hiding places, so when the army returns to the enemy's land, they get the chance to catch them off guard and raid them. The other reason is that when they withdraw from their expedition openly, they cannot be sure that the enemy will not follow their trail and strike them while they are unaware. So sometimes the army, or part of it, reinforces its position by returning along its own tracks partway through the journey, so that if the enemy comes seeking them, they are prepared to meet them, and if not, then they have made it home safely and secured the spoils they were carrying."
