Allah holds the nation responsible for fighting all kinds of corruption (political, economic, social… etc that the nation encounter : And from among you there should be a party who invite to good and enjoin what is right and forbid the wrong, and these it is that shall be successful Be not like those who are divided amongst themselves and fall into disputations after receiving Clear Signs: For them is a dreadful penalty .On the Day when some faces will be (lit up with) white, and some faces will be (in the gloom of) black: To those whose faces will be black, (will be said): “Did ye reject Faith after accepting it? Taste then the penalty for rejecting Faith.

In the light of this, Muslims have to cement Islamic unity to stand in one unified rank against unbelief arrogance, oppression and all wronging. And if they differ about the understanding of certain associates that are related to the doctrine and the juristic rulings or issues of a political and social nature, they have to refer then to Allah and His Messenger.|

The meaning of believing in the two testimonies of believing in the oneness of Allah and in His Messenger is to obey Allah’s commands and in what the Messenger conveys or teaches . We should not accuse each other of unbelief and being led astray, but rather go back to the Book of Allah and the Messenger(pbh)’s Sunna to see what they say.

Allah wants us to establish our relations on the basis of unity and love. We should unify our positions and stands, because the enemies of Allah, His Messenger and the believers have unified to destroy Islam and the Muslims.

And this is what we notice in all the American European and Israeli plots.
The Muslims are no longer in control of their own affairs, rather the arrogant and the unbelievers are the ones who tell them what to do. And, as a result, the Muslims have become fragmented and started killing each other and accusing one another of unbelief. The responsibility therefore is huge, because Allah wants us to be strong and dignified. Imam As-Sadiq says:
“Allah has given the believer the right to run all his affairs, but he did not give him the right to be humiliated”.

We need a trustworthy and faithful internal resistance against those who lie and create strife, and those who practice corruption in the name of reform and change.

Light and Darkness
Imagery of light and darkness occurs frequently in the Qur’an as when faith is likened to light and disbelief to darkness (2:257). The imagery of light and darkness generally occurs with reference to the faces of the two kinds of people on the Day of Judgement:
On the day when some faces will be [lit up with] white, and some faces will be [in the gloom of] black: To those whose faces will be black, [will be said]: “Did ye reject faith after accepting it? Taste then the penalty for rejecting faith.” (3:106)

The darkness covering the faces of the wrong-doers is made manifest by means of a simile here. Their faces would be so dark as if pieces of dark night were covering them.

Some faces that day will be beaming, laughing, rejoicing. And other faces that day will be dust-stained; blackness will cover them: Such will be the Rejecters of Allah, the doers of iniquity. (80:38-42)

Images showing light or darkness also occur with reference to the cosmic upheaval on Doomsday:
At length, when the sight is dazed, and the moon is buried in darkness. And the sun and moon are joined together, That day will man say: “Where is the refuge?” (75:7-10)

Resurrection employs similar imagery:
And the Earth will shine with the Glory of its Lord: the record [of deeds] will be placed [open]; the prophets and the witnesses will be brought forward; and a just decision pronounced between them; and they will not be wronged [in the least]. (39:69)
