Why did Imam Al-Nasa’i’s narration, which includes the statement of Umar ibn Al-Khattab to the one in a state of major ritual impurity (junub), "Do not pray," differ from Imam Al-Bukhari’s narration, which did not mention this statement?

Al-Nasa’i and Al-Bukhari narrated the hadith of Ammar ibn Yasir and Umar ibn Al-Khattab, may Allah be pleased with them, concerning tayammum. They were in a state of janaba and could not find water. Umar ordered them to pray after finding water, while Ammar performed tayammum by rolling in the dust and prayed. When the Prophet, peace and blessings be upon him, was asked, he said to Ammar: "It would have been sufficient for you to do like this," and he struck the ground with his palms, blew on them, and then wiped his face and the back of his hands. There is a discrepancy in the narrations of the hadith regarding the phrase "do not pray" from Umar's statement, as some narrators, like Adam in Al-Bukhari's narration, omitted it, even though the context indicates it. A difference in wording while preserving the meaning is permissible among scholars.
