Hadis Sambhar — Hadith #38248

حَتَّى يَتَبَيَّنَ لَكُمُ الْخَيْطُ الأَبْيَضُ مِنَ الْخَيْطِ الأَسْوَدِ مِنَ الْفَجْرِ\n\nThat is, eat and drink; Until the white thread (white line) of dawn is clearly visible to you from the black thread (black line of the night). (Baqara: 187)\nWhen the said verse was revealed, he (Used on the handkerchief on the head) Put a white and a black thick rope (under the pillow). When night came he noticed, but (which was white and which was black) it was not clear. In the morning he said this to the Messenger of Allah (may peace be upon him).
