Continuation of the discussion on the occasion for this dhikr (O Allah, place light in my heart . . .)

The student : The hadith appears to be regarding the Fajr prayer, not the night prayer, because ... the text of the hadith. So the important point is the phrase: "I stretched out, reluctant for him to see that I had been awake, and I performed wudu'. Then he got up and prayed, and I stood to his left. He took my hand and turned me to his right, and the Prophet's (peace and blessings be upon him) night prayer was completed at thirteen rak'ahs. Then he lay down and slept until he snored, and when he slept, he would snore. Then Bilal came to him and called him to prayer, so he got up and prayed without performing wudu'. And in his supplication was: O Allah "; meaning this was after Bilal came and called him to prayer.
Another student: And in the supplication, where did he supplicate?
The student : After he got up and intended to go to the Fajr prayer, that is it.
Another student: It is categorized under night prayer, meaning you are saying the hadith.
The student : There is no contradiction, there is no contradiction.

The Shaykh : By Allah, what is established in my mind is that this is from the occasion of going out to the mosque for the Fajr prayer.
The student : This is for the Fajr prayer, no, no, the hadith is explicit and in his supplication was, meaning because it is not "was" in the sense of "he had," but "was" in the sense of "it was found in his supplication."
Another student: It was complete, not incomplete.
The student : It was complete, yes.

The Shaykh : Meaning it is not in the sense of "he had supplicated."
The student : No, no, "was" is complete, our Shaykh.
