Al-Nūr (The Light) -Glorified be He
Praising Himself, Allah Almighty says:
{Allah is the Light of the heavens and the earth. The example of His light is like a niche within which is a lamp, the lamp is within a glass, the glass is as if it were a pearly [white] star lit from [the oil of] a blessed olive tree, neither of the east nor of the west, whose oil would almost glow even if untouched by fire. Light upon light. Allah guides to His light whom He wills. And Allah presents examples for the people, and Allah is All - Knowing of all things.}
[Surat an - Nūr: 35]
The Prophet (may Allah’s peace and blessings be upon him) used to make this supplication:
“Allāhumma ij‘al fi qalbi nūran, wa fibasari nūran, wa fi sam‘i nūran, wa ‘an yamīni nūran, wa ‘an yasāri nūran, wa fawqi nūran, wa tahti nūran, wa amāmi nūran, wa khalfi nūran, waj‘al li nūra (O Allah, place light in my heart, light in my sight, light in my hearing, light on my right, light on my left, light above me, light below me, light in front of me, light behind me, and make light for me.)” [Surat a n - Nūr: 35]
[Narrated by Al- Bukhāri and Muslim]
By Allah, this is the most precious thing Allah Almighty may ever give to a servant: His light and guidance.
We are talking here about the provision of hearts and the pleasure of souls. Indeed, this is the greatest, most beneficial, and best provision ever. As a poet says,
Your remembrance keeps it too preoccupied to eat or drink!
Your light illuminates the path for it,
and Your speech is like the pleasant singing of the camel driver,
who reminds the camels of the sweet destination,
and so they do not feel bored or tired of the journey!
