607 – Khallād ibn al-Sāʾib transmits from his father (may Allah be pleased with him) that the Messenger of Allah ﷺ said: “Gabriel came to me and ordered me to tell my Companions to raise their voices when making the ihlāl.” It was narrated by the Five, and both al-Tirmidhī and Ibn Ḥibbān declared it authentic. (1)

Status of the ḥadith
The report is sound (ṣaḥīḥ). The author notes that al-Tirmidhī and Ibn Ḥibbān authenticated it.
In al-Talkhīṣ he adds: It was related by Mālik, al-Shāfiʿī, Aḥmad, the compilers of the Sunan, Ibn Ḥibbān, al-Ḥākim, and al-Bayhaqī from Khallād ibn al-Sāʾib on the authority of his father.
Al-Tirmidhī said: “This ḥadith is sound.”

Glossary
• Ihlāl: The author of al-Mughrib says, “Anything that produces a sound is said to have istahalla.” Abū’l-Khaṭṭāb remarks, “Anyone who speaks—whether loudly or softly—is a muhill or mustahill.” In al-Nihāyah Ibn al-Athīr defines it as “raising the voice with the talbiyah,” giving a concrete example of the broader linguistic meaning. Al-muhill (with ḍamma on the mīm) can denote the place where the proclamation of consecration is made, and it may also refer to the time of that act or to the verbal noun itself.

Points derived from the ḥadith
1 – Some scholars have taken this ḥadith as proof that pronouncing the talbiyah is obligatory because it comes in the form of a command; among those who hold this view are Abū Ḥanīfah and the majority.
