“Jibril came to me and said: ‘O Muhammad! Tell your Companions to raise their voices when reciting the Talbiyah, for it is one of the symbols of Hajj.’” (Using translation from Ibn Mājah 2923)
عَنِ النَّبِيِّ ﷺ قَالَ جَاءَنِي جِبْرِيلُ فَقَالَ مُرْ أَصْحَابَكَ فَلْيَرْفَعُوا أَصْوَاتَهُمْ بِالتَّلْبِيَةِ فَإِنَّهَا مِنْ شِعَارِ الْحَجِّ
