Nor indeed can we explain the Qur'anic verse with reference to Malik Ibn Nuwayrah and his followers, who refused to pay Zakat (alms) in the time of the caliph Abu Bakr, for many reasons.
They refused to pay al-Zakat (alms) and give it to Abu Bakr because they wanted to wait and see what happened, for they had accompanied the Messenger of Allah on his farewell pilgrimage, and voted for Imam ‘Ali ibn Abi Talib at Ghadir Khum after the Messenger of Allah appointed him as Caliph after him, and indeed Abu Bakr himself voted for ‘Ali.
Therefore, they were astonished when a messenger from the caliph came to tell them the news of the holy Prophet's death and at the same time asked them to pay Zakat in the name the new caliph, Abu Bakr. It is a case in which history does not want to go too deep, for the sake of the Companion's honor. Furthermore, Malik and his followers were Muslims according to the testimony of Umar and Abu Bakr themselves and other who disapproved of Khalid ibn al-Walid's killing of Malik.
History testifies that Abu Bakr paid compensation for Malik's death to his brother Mutammem out of the Muslim's treasury, and apologized for his killing. It is well established that the apostate must be killed, and no compensation be paid out of the Muslim's treasury for his killing, and no apologies issued for killing him.
The important thing is that the "turning back" verse refers to the who lived with the Messenger of Allah in al-Medinah al- Munawwarah, and indicates the immediate "turning back" after the Prophet's death. The Prophet's sayings explain all these things in such a clear way, that no one could doubt it. We shall deal with these matters soon, if Allah wills.
History also testifies for the "turning back" that happened after the death of the Messenger of Allah, and when we view the events which took place among the ranks of the we notice that only a few managed to come out unscathed. The Holy War (Jihad) Verse Allah, the Most High, said: "O You who believe, what (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the Hereafter?
But the provision of this world's life compared with the Hereafter is but little. If you do not go forth, He will chastise you with a painful chastisement and bring in your place a people other than you, and you will do Him no harm; and Allah has power over all things" (Holy Qur'an 9:38-39).
