[Machine] The Messenger of Allah ﷺ said, "The call to prayer (adhan) by Bilal should not prevent you from having the pre-dawn meal (suhur), nor should the elongated dawn (fajr) prevent you, but rather the elongated dawn (fajr) is in the horizon." And the exact wording is from Hajjaj ibn Nusayr.
قَالَ رَسُولُ اللهِ ﷺ «لَا يَمْنَعْكُمْ مِنَ السُّحُورِ أَذَانُ بِلَالٍ وَلَا الصُّبْحُ الْمُسْتَطِيلُ وَلَكِنِ الصُّبْحُ الْمُسْتَطِيلُ فِي الْأُفُقِ» وَاللَّفْظُ لِحَجَّاجِ بْنِ نُصَيْرٍ
