Most of the Bedouin Arabs who had earlier rallied out of FEAR to the banner of 'Islam' under Muhammad, changed their mind after his death.
It took almost two years of bloody fighting under the first Khalifa, Abu Bakr and under the generalship of Khalid Ibn al Walid (The Sword of Allah) to subdue, subjugate and force those sessessionists and apostates to return - once more - to the fold of 'Islam' at the point and edge of the sword.
Contrary to all the platitudes and falsifications of the historical record conducted by the followers of Muhammad, his 'Islam' was born by the bloodshedding of swords and continues to this day in the same manner.
We alighted at a camping-place along with Allah's Messenger (peace be upon him), and when the people began to pass he was asking, "Who is this, AbuHurayrah?" and I would tell him it was so and so. He would then say, "This is a good servant of Allah." He would ask about another, and when I told him he was so and so he said, "This is a bad servant of Allah." This went on till Khalid ibn al-Walid passed by, and when he asked who he was and I replied that he was Khalid ibn al-Walid, he said, "Khalid ibn al-Walid is a good servant of Allah; he is one of Allah's swords." Tirmidhi transmitted it.
Sahih Al-Bukhari HadithHadith 5.561Narrated byAnas
The Prophet had informed the people of the martyrdom of Zaid, Ja'far and Ibn Rawaha before the news of their death reached. The Prophet said, "Zaid took the flag (as the commander of the army) and was martyred, then Ja'far took it and was martyred, and then Ibn Rawaha took it and was martyred." At that time the Prophet's eyes were shedding tears. He added, "Then the flag was taken by a Sword amongst the Swords of Allah (i.e. Khalid) and Allah made them (i.e. the Muslims) victorious."
Sunan of Abu-DawoodHadith 4403Narrated byUbadah ibn as-Samit
The tradition mentioned above (No. 4401) has also been transmitted by Ubadah ibn as-Samit through a different chain of narrators. This version has: The people said to Sa'd ibn Ubadah: AbuThabit, the prescribed punishments have been revealed: if you find a man with your wife, what will you do? He said: I shall strike them with a sword so much that they become silent (i.e. die). Should I go and gather four witnesses? Until that (time) the need would be fulfilled. So they went away and gathered with the Apostle of Allah (peace be upon him) and said: Apostle of Allah! did you not see AbuThabit. He said so-and-so. The Apostle of Allah (peace be upon him) said: The sword is a sufficient witness. He then said: No, no, a furious and a jealous man may follow this course.
Sahih Al-Bukhari HadithHadith 4.210Narrated bySalim Abu An Nad
The freed slave of 'Umar bin 'Ubaidullah who was 'Umar's clerk: 'Abdullah bin Abi Aufa wrote him (i.e. 'Umar) a letter that contained the following:
"Once Allah's Apostle (during a holy battle), waited till the sun had declined and then he got up among the people and said, "O people! Do not wish to face the enemy (in a battle) and ask Allah to save you (from calamities) but if you should face the enemy, then be patient and let it be known to you that Paradise is under the shades of swords." He then said, "O Allah! The Revealer of the (Holy) Book, the Mover of the clouds, and Defeater of Al-Ahzab (i.e. the clans of infidels), defeat them infidels and bestow victory upon us."
*** Muhammad and his Quran never miss a chance to show their warmongering, hatefilled and destructive natures in hundreds of verses wishing death, destruction, plundering or subjugation of most of humanity unless and until they believe that Muhammad is the messenger of Allah.
Even Paradise, the alleged abode of the Allah is decked with the instruments of death and destruction.
There is nothing in the Quran which shows a path to true salvation or redemption especially since all of Allah's creation is PRE-DESTINED and has no FREE WILL or choice ***
