The Witness, The One who nothing is absent from Him.

Say: “Allah is a sufficient witness between me and you. He is certainly aware of and sees His servants.” (Surat al-Isra’, 17:96)

Allah has no beginning and no end, is the sole absolute Being, and is not bound by such human concepts as time or space. Therefore, everything that ever happens, regardless of whether it happened in the past, the present, or the future, are the same in— and are fully known to—His Sight.

He knows everything, whether it is done in secret or in public, in darkness or in light, while alone or while in a crowd. Being ignorant, people assume that what they do at night might conceal their sins and hide them as well. But such hopes are futile, for the Qur’an states:

"Do you not see that Allah knows what is in the heavens and on Earth? Three men cannot confer together secretly without Him being the fourth, or five without Him being the sixth, or fewer than that or more without Him being with them wherever they are. Then He will inform them on the Day of Rising of what they did. Allah has knowledge of all things." (Surat al-Mujadala, 58:7)

Allah is fully knowledgeable of everyone’s intentions, thoughts, and deeds at every one moment. Each of us will be called to account for all of these on the Day of Judgment. People who deny these truths will understand their mistake on the Day of Judgment. As “On the Day Allah raises up all of them together, He will in- 221 form them of what they did. Allah has recorded it while they have forgotten it. Allah is a Witness of all things” (Surat al-Mujadala, 58:6)
