What is the meaning of the Hadith, "Indeed, I narrate to you a Hadith today," especially the part related to "and he would make his family perform Umrah during the ten days"?

The Hadith of 'Imran ibn Husayn includes three matters:

1. The best of Allah's servants are those who praise Him profusely: This means those who frequently praise Allah in times of ease and hardship. This statement is attributed to 'Imran (may Allah be pleased with him).

2. A group from my Ummah will continue to fight for the truth: They will be victorious and triumphant, or known and renowned. They are dispersed among various types of believers, and it is not necessary for them to be gathered together.

3. The Prophet's performance of 'Umrah with his family during the ten days: Meaning he had them perform 'Umrah during the first ten days of Dhul-Hijjah, clarifying that this is permissible. He also explained that 'Umar ibn Al-Khattab's prohibition of Mut'ah (temporary marriage or combining Hajj and 'Umrah) was his own Ijtihad (independent reasoning) to ensure the Sacred House (Kaaba) remained populated throughout the year, and was not a prohibition of it.
