اللّٰهُمَّ اجْعَلْ فِيْ قَلْبِيْ نُوْرًا وَّفِيْ لِسَانِيْ نُوْرًا وَّاجْعَلْ فِيْ سَمْعِيْ نُوْرًا وَّاجْعَلْ فِيْ بَصَرِيْ نُوْرًا وَّاجْعَلْ مِنْ خَلْفِيْ نُوْرًا وَّمِنْ اَمَامِيْ نُوْرًا وَّاجْعَلْ مِنْ فَوْقِيْ نُوْرًا وَّمِنْ تَحْتِيْ نُوْرًا ، اللّٰهُمَّ اَعْطِنِيْ نُوْرًا

O Allah! Place light in my heart, and in my tongue, in my hearing and in my sight; let there be light behind me and in front of me, light above me and below me. O Allah, grant me light.

Sahih Muslim, (2/530) no. (763), Darussalam numbering (1799). The original book has further words on the authority of several hadiths; we have given only the wording of the hadith of Sahih Muslim that states clearly that the Prophet of Allah ﷺ said them while going out for the prayer.
The narrators of this hadith differed about when the Prophet ﷺ said this supplication. Hafiz Ibn Hajar (RH) reconciled all the narrations by explaining that the Prophet of Allah ﷺ said it on every occasion mentioned in the narrations. See: [Nata'ij al-Afkar of Ibn Hajar (1/266)]
Zubair Ali Zai wrote:
“This supplication is general; it has nothing to do with going to the mosque” [Hisn al-Muslim, takhrij of Zubair Ali Zai: page (40)]
The reply is that the hadith of Sahih Muslim clearly says:
“فأذن المؤذن **فخرج إلى الصلاة**، وهو يقول:اللهم اجعل في قلبي نورا....الخ”
“The muezzin called the adhan, then he ﷺ went out for the prayer while saying: اللهم اجعل في قلبي نورا ....” [Sahih Muslim (3/530) no. (763)]; see also: [al-Jami' al-Kamil of al-A'zami (9/534)]
So it is wrong to say that “it has nothing to do with going to the mosque”.
