He was present during the
Expedition of Dhat al-Riqa. Some scholars claim that the expedition took place in
Nejd (a large area of tableland in the Arabian Peninsula) in Rabi‘ Ath-Thani or Jumada Al-Ula, 4 A.H (or beginning of 5AH). They substantiate their claim by saying that it was strategically necessary to carry out this campaign in order to quell the rebellious bedouins in order to meet the exigencies of the agreed upon encounter with the polytheists, i.e. minor Badr Battle in Sha‘ban, 4 A.H. Muhammad received the news that certain tribes of
Banu Ghatafan were assembling at
Dhat al-Riqa with suspicious purposes. Muhammad proceeded towards
Nejd at the head of 400 or 700 men, after he had mandated
Abu Dhar - in the Umayyad version, the Umayyad chief :
Uthman ibn Affan was given this honor- to dispose of the affairs of
Madinah during his absence. The Muslim fighters penetrated deep into their land until they reached a spot called Nakhlah where they came across some bedouins of Ghatfan. The most authentic opinion according to "Saifur Rahman al Mubarakpuri", however, is that Dhat Ar-Riqa's 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 which Muhammad observed at Dhat Ar-Riqa's campaign, were revealed at the
Asfan Invasion which scholars say, took place after Al-Khandaq (the
Battle of the Trench). ==After the Caliphate of Abu Bakr==
