حَتَّىٰ يَتَبَيَّنَ لَكُمُ الْخَيْطُ الْأَبْيَضُ مِنَ الْخَيْطِ الْأَسْوَدِ مِنَ الْفَجْرِ
Until the white thread of dawn becomes distinct to you from the black thread.
The image of a white and black thread does not literally mean two pieces of cloth thread for determining the fast. “of dawn” and prophetic explanation clarify the light of dawn and the darkness of night.
Literal meanings matter, but proper interpretation also requires context, linguistic indicators and reliable explanation. Isolating one word may distort a religious ruling.
