[Machine] The Messenger of Allah ﷺ said, "Do not be deceived by the call of Bilal and this whiteness, until the dawn breaks or the day breaks forth."
قَالَ رَسُولُ اللهِ ﷺ لَا يَغُرَّنَّكُمْ نِدَاءُ بِلَالٍ وَهَذَا الْبَيَاضُ حَتَّى يَنْفَجِرَ الْفَجْرُ أَوْ يَطْلُعَ الْفَجْرُ
Neither the call of Bilal should mislead you nor this whiteness (of false dawn) till (the true) dawn appears (or he said) till the dawn breaks.
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لاَ يَغُرَّنَّكُمْ نِدَاءُ بِلاَلٍ وَلاَ هَذَا الْبَيَاضُ حَتَّى يَبْدُوَ الْفَجْرُ أَوْ قَالَ حَتَّى يَنْفَجِرَ الْفَجْرُ
"The Messenger of Allah said; 'DO not be confused by the Adhan of Bilal, or by this whiteness, until dawn appears like this" - meaning horizontally. (One of the narrators) Abu Dawud said: "And he spread out his hands gesturing to the right and left."
قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَغُرَّنَّكُمْ أَذَانُ بِلاَلٍ وَلاَ هَذَا الْبَيَاضُ حَتَّى يَنْفَجِرَ الْفَجْرُ هَكَذَا وَهَكَذَا يَعْنِي مُعْتَرِضًا
