عَنْ خَلَّادِ بْنِ السَّائِبِ بْنِ خَلَّادٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((أَتَانِي جِبْرِيلُ عَلَيْهِ السَّلَامُ فَقَالَ: مُرْ أَصْحَابَكَ فَلْيَرْفَعُوا أَصْوَاتَهُمْ بِالْإِهْلَالِ))
It is narrated from Sayyiduna Sa’ib bin Khallad (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Jibreel (peace be upon him) came to me and said: Command your companions to raise their voices when reciting the Talbiyah.
