Dear Islamic brothers! From this, it is known that the beloved Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, is himself light, and by the grace of Allah Almighty, every child in his pure progeny is also light.

Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ  is called Dhū al-Nūrayn, the possessor of two lights, because two daughters of the beloved Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم (i.e., Sayyidatunā Ruqayyah and Sayyidatunā Umm Kulthūm رَضِیَ اللهُ عَنْهُمَا), came into his marriage. This means that these two daughters of the beloved Prophet              صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم are light, and since they came into the marriage of Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ, he became the possessor of two lights.

So, we learn that holding the belief that the daughters of the beloved Prophetصَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم are light is not only the belief of the Companions رَضِیَ اللهُ عَنْهُم, but even that of the angels call, as they called Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ Dhū al-Nūrayn. This means that even the angels believe that the noble Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم is himself light, and his progeny is also light.

Dear Islamic brothers! Some other reasons for calling Sayyidunā ꜤUthmān      رَضِىَ اللّٰهُ عَـنْهُ Dhū al-Nūrayn have also been stated by the respected scholars:

Second Reason for the Dhū al-Nūrayn

(2) The scholars state: It is the distinction of Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ that on the Day of Judgement, when he رَضِىَ اللّٰهُ عَـنْهُ enters Paradise, two lights will shine brightly to welcome him in Paradise. That is why he is called Dhū al-Nūrayn.^[1]

Third Reason for the Title Dhū al-Nūrayn

(3): Imam Abū Ḥusayn Qazwīnī رَحْمَةُ الـلّٰـهِ عَـلَيْه states: It was the noble practice of Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ to recite the entire Holy Quran in his Witr prayer.

Since the Holy Quran is light and standing in prayer at night is also light, and Sayyidunā ꜤUthmān رَضِىَ اللّٰهُ عَـنْهُ used to combine these two lights, that is why he
