[6] After the death of the Prophet of Islam, Muhammad, on June 8, 632[8],,[9] Abu Bakr As-Siddiq was appointed as the successor to lead the newly emerging state.

In his work Khalid Bin Al-Waleed Sword Of Allah,[n 7] Agha Ali Ibrahim Akram relates that about a week or two after the departure of Usama bin Zayd's army[11],,[n 8] delegates from the apostates of Dhu al-Qassah[n 9] came to Abu Bakr As-Siddiq in Medina[11],[14],[19],,[20] and declared: We continue to pray, but we no longer pay the tax[11],[21],.

[n 11]The next morning, before the one-day ultimatum expired, the emissaries discreetly left Medina, signaling their rejection of Abu Bakr As-Siddiq's demands[3],.

[14] Shortly after their departure, Abu Bakr As-Siddiq sent his own emissaries to all the apostate tribes, urging them to remain faithful to Islam and continue paying their taxes, which did not have the desired effect.

[25] Upon their return, they reported to their compatriots about the conversation with Abu Bakr As-Siddiq and the apparent vulnerability of Medina[3],[14],[24],,[25] however, although Usama bin Zayd's main army had not yet returned from its expedition, the city was not as defenseless as the apostates thought, as there were still many able-bodied men, particularly from the Banu Hashim clan,[n 12] who had stayed behind to mourn their deceased relatives.

[25] Abu Bakr As-Siddiq rejected this proposal, stating: If they refuse me even the halter of a camel, I will fight them for it[11],[22],[14],[n 15]He issued an ultimatum[17],,[3] giving the delegations one day and one night to accept his conditions[17],[3],.

[3] Upon their return, they reported the small number of defenders in Medina[14],[3],,[25] thus arousing the covetousness of the city among their compatriots and prompting them to prepare for an attack[14],[3],.

[27] Abu Bakr As-Siddiq then decided, on his order, to have the Muslims leave Medina to launch a swift attack on the apostates' forward camp.

[27] Less than three days later, the apostate forces launched a nighttime attack on Medina, leaving half of their men at Dhu Husa as a reserve.

[26] Abu Bakr As-Siddiq ordered them to hold their positions, which they did, while the caliph led the inhabitants from the mosque, mounted on their pack camels.

[26] In his work Biographies of the Rightly Guided Caliphs,[28] Tamir Abu Suood Muhammad relates that after three days, the apostate rebels began to move actively within the Dhu Husa camp.

Leading a contingent, Abu Bakr As-Siddiq took position at a strategic point facing Dhu Husa, where the attack was expected to occur.

As the apostate forces advanced in the darkness of the night, Abu Bakr As-Siddiq's contingent fell upon them, taking them by surprise.

[27] Hibal ibn Khuwailid, having repelled the Muslims without truly engaging in battle, interpreted their retreat as a sign of fear, not realizing that the camels' panic was the real cause.

[4] The Muslims pursued the apostate cavalry on their pack camels to Dhu Husa,[26] where the enemy reserves suddenly appeared with inflated goatskins, tied with ropes.

[31] The Muslims, furious and determined to take revenge, learned that the apostates had returned to their camp near Medina and decided to attack them before they could finalize their battle preparations.

[1] During the last part of the night, Abu Bakr As-Siddiq led his army out of Medina and deployed it in an assault formation, with a center, two flanks, and a rear guard.

[1] After capturing Dhu al-Qassah[33],,[1] Abu Bakr As-Siddiq sent a small force under the command of Talha ibn Ubayd Allah to pursue the enemy.

[1] Talha ibn Ubayd Allah advanced a short distance and eliminated some stragglers,[1] but the small size of his contingent limited his ability to inflict significant losses on the retreating apostates.

[1] Muhammad ibn Jarir al-Tabari does not detail the events of the fourth confrontation as extensively as his counterpart Agha Ali Ibrahim Akram.

Abu Bakr As-Siddiq left Al-Nu'man ibn Muqrin with a unit to occupy Dhu al-Qassah, while he returned to Medina with the rest of his army[1],[34].

[1] Abu Bakr As-Siddiq appointed Al-Nu'man ibn Muqrin to lead a portion of the troops at Dhu al-Qassah, then returned to Medina[34],.

Adding 40 to 60 days aligns with the accounts of Agha Ali Ibrahim Akram, who places the return of Usama bin Zayd's army on August 2, 632.

Building on this success, the fourth confrontation, led by Abu Bakr As-Siddiq, results in the retreat of the apostate rebels from Dhu al-Qassah to the Abraq area.

Abu Bakr As-Siddiq vowed that in retaliation for each Muslim killed, he would eliminate an equivalent or even greater number of apostate rebels from each tribe[34],.
