Samura b. Jundub reported Allah's Messenger (ﷺ) as saying: The Adhan of Bilal should not mislead you nor the whiteness (of the pillar) of dawn, for it is not the whiteness of the true dawn, but that of the false dawn which is vertical like a pillar and you can eat food till the streaks of whiteness spread like it.

وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ سَوَادَةَ، عَنْ أَبِيهِ، عَنْ سَمُرَةَ بْنِ جُنْدَبٍ، - رضى الله عنه - قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ يَغُرَّنَّكُمْ أَذَانُ بِلاَلٍ وَلاَ هَذَا الْبَيَاضُ - لِعَمُودِ الصُّبْحِ - حَتَّى يَسْتَطِيرَ هَكَذَا ‏"‏‏.‏
