The Salaf, the Companions, and the Tabi'un: We see that they say "al-ihlal," but in the present time, the scholars say "al-ihram"?

The questioner : May Allah reward you. Whoever reads the words of the righteous Salaf, the Companions and the Tabi'un, sees that they say... "al-ihlal." But in the present time, we see that the scholars say "al-ihram"?

The Shaykh : "Al-ihlal"?

The questioner : "Al-ihlal."

The Shaykh : How is "al-ihlal" and what does it mean?

The questioner : For example, the hadith:
The Shaykh: Yes, "ahalla" means he responded with the talbiyah. "Al-ihlal" is raising the voice with the talbiyah. Yes.
