Sibghat
Yes, the word appears in Surah Al-Baqarah 2:138 referring to the 'dye/nature of Allah', though as a personal name it is derived from this verse.
It refers to the innate spiritual disposition (fitrah) that Allah instills in every human, coloring their soul with natural monotheism.
It appears primarily in Urdu-speaking regions of South Asia and among Pashto speakers, though it remains rare compared to other Quranic names.
While grammatically feminine in Arabic (صبغة), it is traditionally used for boys in South Asian Muslim communities when referring to the Quranic concept.
Sibghatullah means 'the dye/nature of Allah', while Sibghat is the concise form meaning 'dye/nature' or 'innate quality'.
