Abu Hurairah
However, Safiur Rahman Mubarakpuri claimed that Dhat Ar-Riqa‘ campaign took place after the fall of Khaibar (and not as part of the Invasion of Nejd). This is supported by the fact that Abu Hurairah and Abu Musa Ashaari witnessed the battle. Abu Hurairah embraced Islam only some days before Khaibar, and Abu Musa Al-Ash‘ari came back from Abyssinia (Ethiopia) and joined Muhammad at Khaibar. The rules relating to the prayer of fear that Muhammad observed at Dhat Ar-Riqa‘ campaign, were revealed at the Asfan Invasion. Scholars say that this took place after Al-Khandaq (the Battle of the Trench).
