Invasion of Nejd
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.
Background and Invasion
After the Invasion of Banu Nadir, resulting in the expulsion of the Banu Nadir Jews, Muhammad stayed in Medina for two months. Then he received the news that certain tribes of Banu Ghatafan were assembling at Dhat al Riqa with suspicious purposes. The Ghatafan were an Arabian tribe, descended from Qais.
Meanwhile, the Muslim scouting groups reported building up of bedouin troops of Bani Muharib and Tha‘labah of Ghatfan around Madinah. According to the Sealed Nectar, Muhammad, with his Muslim warriors, hurriedly set out to discipline these new outlaws, cast fear into their hearts and deter them from perpetrating further practices. These deterring operations were carried out repeatedly and did produce effective results. The Bedouins fled into the mountains, and Madinah became immune to their raids.
