This should be taken in it own context in time and space:
During the Islamic Prophet
Muhammad's era, Muhammad carried out military expeditions in the area. The first was the
Nejd Caravan Raid against the
Quraysh, which took place in 624. The Meccans led by Safwan ibn Umayyah, who lived on trade, left in summer for Syria for their seasonal trade business. After Muhammad received intelligence about the Caravan's route, Muhammad ordered
Zayd ibn Haritha to go after the Caravan, and they successfully raided it and captured 100,000
dirhams worth of booty.
The
Invasion of Nejd, happened in Rabi‘ Ath-Thani or Jumada Al-Ula, 4 A.H i.e. in October, 625 AD.
Muhammad led his fighters to Nejd to scare off some tribes he believed had suspicious intentions. Some scholars say the
Expedition of Dhat al-Riqa took place in Nejd as part of this invasion.
The most authentic opinion according to "Saifur Rahman al Mubararakpuri", however, is 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 Al-Ash‘ari 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‘ campaign, were revealed at the
Asfan Invasion and this scholars say, took place after Al-Khandaq (the
Battle of the Trench).
The
Expedition of Qatan also took place in Nejd. Banu Asad ibn Khuzaymah tribe (not to be confused with the
Banu Asad tribe), were the residents of
Katan, in the vicinity of
Fayd, was a powerful tribe connected with the Quraysh. They resided near the hill of Katan in
Nejd. Muhammad, received intelligence reports that they were planning a raid on Medina. So he dispatched a force of 150 men under the leadership of
Abu Salama `Abd Allah ibn `Abd al-Asad to make a sudden attack on this tribe.
