All in all...
All in all, the verse has such a broad meaning which involves all, the above commentaries, though some of its examples are clearer and more important than the others. Some have considered its meaning even beyond this and have said that the objective point for the term 'break of dawn' is 'any light that glitters in the dark’. Therefore, the glitter of the light of Islam and Muhammad (S) in the gloom of ignorance at that time, is one of the examples of /fajr/ ‘break of dawn'.
Also, the glitter of the break of dawn for the Rise of Hazrat Mahdi (the twelfth Imam) (as), when the world will be completely darkened by corruption. transgression and injustice, is considered to be another example of this[^3] The rise of Imam Husain (as) on the bloody plains of Karbala, is another example, when he pulled back the black curtains of deceit revealing the tyrannies of the Ummayides and unveiling the real face and nature of those devils.
Furthermore, all the true revolutions that have occurred in the history of the world, against disbelief, ignorance, transgression and cruelty are, also, examples of /fajr/. Even the first light of wakefulness that appears in the darkened hearts of sinners and makes them move to repent, is /fajr/ ‘break of dawn'. Of course, this is an expansion on the concept of the verse, while the apparent meaning of the verse has the same meaning /fajr/ with the sense of 'the break of dawn’.
The oath 'By the Ten Nights' is generally understood to be the first ten nights of Zul-Hajj; nights which are witness to the largest and most devoted gathering of Muslims in the world, and this is an idea which is narrated by Jabir-ibn-' Abdillah in a tradition from the Prophet (S).[^4] Some have also commented on them to mean 'the last ten nights of Ramadan' in which the nights of /qadr/, (when the Qur'an was revealed) are hidden:.
Some have meant 'the Ten Nights' to be the first ten nights of Muharram; the first Arabic lunar month. It is also possible to combine these three commentaries together. Some narrations, containing the hidden meanings of the Qur'an. say that /fajr/ refers to the existence of Imam Mahdi (as), and /layalin-'asr/ ‘ten nights' refers to the ten sinless Imams who came before him (as), and /saf'/’ even' refers to Hazrat Ali (as) and Fatimah Zahra (sa); the latter term is mentioned in the next verse.
In any event, the oath to these ten nights is an evidence of their great importance, since oaths are always made to very important things.
