Ibn Majah

Commentary:
(1)
The mention of parents and the meaning of combining them is that the Prophet sallallahu alayhi wa sallam addressed Zubair bin al-Awwam radi Allahu anhu and said:
“My mother and father be sacrificed for you.”
Due to his bravery in battle, the Prophet sallallahu alayhi wa sallam used these words to encourage him.
It is narrated in Sahih al-Bukhari that the Prophet sallallahu alayhi wa sallam also combined his parents for Zubair when he brought news about Banu Qurayza. (Sahih al-Bukhari, Virtues of the Companions of the Prophet sallallahu alayhi wa sallam, Chapter: The Virtues of Az-Zubair...etc., Hadith: 3720)

(2)
During the Battle of Uhud, the Prophet sallallahu alayhi wa sallam also said to Sa’d bin Abi Waqqas radi Allahu anhu:
“Shoot (arrows)! My mother and father be sacrificed for you.” (Sahih al-Bukhari, Book of Manners, Chapter: The Statement of a Man, ‘May my father and mother be sacrificed for you’, Hadith: 6184)

(3)
Both Zubair and Sa’d bin Abi Waqqas radi Allahu anhuma are included among the ten who were given glad tidings of Paradise (al-‘asharah al-mubashsharah).

Explanation:
➊: And this is evidence of the great closeness of Zubair to the Messenger of Allah (sallallahu alayhi wa sallam).
