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. (Using translation from Abū Dāʾūd 1814)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ أَتَانِي جِبْرِيلُ عَلَيْهِ السَّلَامُ فَقَالَ أَنْ آمُرَ أَصْحَابِي أَوْ مَنْ مَعِي أَنْ يَرْفَعُوا أَصْوَاتَهُمْ بِالتَّلْبِيَةِ أَوْ بِالْإِهْلَالِ يُرِيدُ أَحَدَهُمَا
