Khalid ibn as-Sa'ib al-Ansari on his father's authority reported the Messenger of Allah ﷺ as saying: Gabriel came to me and commanded me to order my Companions to raise their voices in talbiyah.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَتَانِي جِبْرِيلُ ﷺ فَأَمَرَنِي أَنْ آمُرَ أَصْحَابِي وَمَنْ مَعِي أَنْ يَرْفَعُوا أَصْوَاتَهُمْ بِالإِهْلاَلِ أَوْ قَالَ بِالتَّلْبِيَةِ يُرِيدُ أَحَدَهُمَا
