The agreement stipulated that in the event of any aggression against a tribe that had chosen a particular alliance, the party to which it was allied would possess the right to take retaliatory action.
[6] They had maintained peace for a period of time; however, underlying motives stemming from the pre-Islamic era, exacerbated by a persistent desire for revenge, ultimately led to renewed hostilities.
In response, the Banu Khuza'ah immediately dispatched a delegation to Medina to inform Muhammad of the breach of the truce and to request his assistance.
Three demands were presented, the acceptance of any one of which was imperative: This behaviour by the Quraysh was a clear breach of the Treaty of Hudaybiyyah and a hostile act against the Muslim allies, the Banu Khuza'ah.
Realizing the gravity of the situation and the potential consequences, the Quraysh immediately called for an emergency meeting and elected to send their leader, Abu Sufyan ibn Harb, to Medina for the renegotiation of the treaty.
Finally, he turned to 'Ali bin Abi Talib, pleading with him in the humblest manner and subtly hinting at the potential for domination over all the Arabs if he were to intercede for the renewal of the treaty.
[6] According to Al-Tabari, three days prior to receiving news of a breach of covenant, Muhammad instructed his wife, 'Aisha, to make preparations for a military campaign.
On the third day, 'Amr bin Salim Al-Khuza'i arrived in Medina with a group of 40 horsemen to inform Muhammad of the plight of his people and to seek assistance from the Muslims for retaliation.
With the aim of ensuring a total news blackout regarding his military plans, Muhammad dispatched a small unit of eight individuals, led by Abu Qatadah bin Rab'i, towards the vicinity of Edam, close to Medina, with the intent of diverting the people's attention and obscuring the true objective of his focus.
[6] There was so much fear everywhere that Hatib, a trusted follower of Muhammad, secretly sent a female messenger to Mecca with a letter that contained information of the intended attack by the Muslims.
"[6][8][9][10][11][12][13] Muhammad set out towards Mecca at the head of an army consisting of ten thousand soldiers on the tenth day of the month of Ramadan.
As they progressed towards Mecca, Al-'Abbas bin 'Abdul Muttalib and his family joined Muhammad and his army at a place called Al-Juhfa.
This was done to allow the Quraysh to accurately assess the situation and make informed decisions, rather than risking their lives by blindly entering into the battlefield without proper knowledge.
"[6] On the morning of Tuesday, 17th Ramadan, 8 A.H., Muhammad set out from Mar Az-Zahran and ordered 'Abbas to detain Abu Sufyan ibn Harb at a location that offered a clear view of the Muslim army's march towards Mecca.
When he passed by Abu Sufyan ibn Harb, he taunted him, saying "Today will witness the great fight, you cannot seek sanctuary at Al-Ka'bah.
"[6] Abu Sufyan expressed his dismay to Muhammad, who became angry and rebuked Sa'd, stating "Nay, today Al-Ka'bah will be sanctified, and Quraysh honoured.
He appointed Khalid ibn al-Walid as the leader of the right flank of the army with the Aslam, Sulaym, Ghifar, Muzainah, and Juhaynah tribes under his command to enter Mecca through its lower avenues.
The soldiers were given clear and decisive orders not to kill unless in self-defense, and to eliminate any aggressive elements and quell any opposition they may encounter.
Zubayr ibn al-Awwam reached his designated destination, where he planted the banner at the Al-Fath (conquest) Mosque and waited there for the arrival of Muhammad.
(Qur'an 17:81)[6][20]This act was significant as it symbolized the removal of polytheistic practices and the reclaiming of the Kaaba for the worship of Allah alone, in line with the teachings of Islam.
[6] Muhammad then entered the sacred hall, facing the wall opposite the door and performed devout prostrations, and went around acclaiming the Greatness and Oneness of Allah.
Shortly afterwards, he returned to the doorway, standing on its elevated step, gazed in thankfulness at the thronging multitude below and delivered a celebrated address:[6][21] "There is no god but Allah Alone.
Bear in mind that every claim of privilege, whether that of blood, or property, is under my heel, except that of the custody of Al-Ka'bah and supplying of water to the pilgrims.
One of the individuals killed was 'Abdullah ibn Khatal, who had initially accepted Islam and was appointed to collect alms-tax (zakat) in the company of an Ansar.
Wahshi, the murderer of Hamza ibn Abd al-Muttalib, Muhammad's uncle, and Hind bint Utba, who had mutilated his body, were also extended clemency.
Habar, who had attacked Muhammad's daughter with a spear while she was on her way from Mecca to Medina, causing fatal injuries that ultimately led to her death, was also forgiven.
It is not allowed to uproot its shrubs or to cut its trees, or to chase (or disturb) its game, or to pick up its fallen things except by a person who would announce that (what has found) publicly."
Additionally, he granted the family of the victim the right to choose between two options for redress: the payment of blood-money or the pursuit of just retribution through the death of the perpetrator.
Muhammad, with 'Umar bin Al-Khattab acting as his representative, accepted their allegiance on the condition that they would not associate any other deity with Allah and that they would not engage in theft.
Muhammad stayed in Mecca for nineteen days during which he focused on educating people about the principles of Islam and guiding them towards the correct path.
