Benefits and Issues:
This narration is also found in Sahih Bukhari with similar wording.
("By the life of Allah, we will surely kill him") (Sahih Bukhari,
Book of Oaths and Vows,
Chapter: The Statement of a Man: By the Life of Allah,
Hadith 6662). Hafiz Ibn Hajar has said that "life" (ʿumr) here means existence.
The one who swears by this word is swearing by the everlastingness of Allah.
And everlastingness (baqa) is an intrinsic attribute of Allah.
Therefore, to swear in this manner is correct.
(Fath al-Bari,
the aforementioned chapter)
