´It was narrated from 'Asim bin Sufyan Ath-Thaqafi that they went out for the battle of As-Salasil, but they missed the fighting, so they kept watch, then they went back to Mu'awiyah, and Abu Ayyub and 'Uqbah bin 'Amir were with him. 'Asim said:` "O Abu Ayyub, we missed the general mobilization, but we have been told that whoever prays in the four Masjids will be forgiven his sins." He said: "O son of my brother! I will tell you of something easier than that. I heard the Messenger of Allah (ﷺ) says: 'Whoever performs Wudu' as commanded and prays as commanded, will be forgiven for his previous actions.' Is it not so, O 'Uqbah?" He said: "Yes."

Brief Explanation
“Ghazwah Salasil”: This is not the same expedition that took place during the time of the Noble Prophet (sallallahu alayhi wa sallam) in 8 AH; rather, it was an expedition that occurred during the era of Umar ibn al-Khattab (radi Allahu anhu) within the land of Iraq.
2؎: By the four mosques are meant: Masjid al-Haram, Masjid al-Nabawi, Masjid Quba, and Masjid al-Aqsa.
