"We used to pledge to the Messenger of Allah (ﷺ) to hear and obey." So he would say to us: "As much as you are able."

This Hadith is Hasan Sahih.
Jami` at-Tirmidhi Book 21, Hadith 55
← Previous Hadith "I said to Salamah bin Al-Akwa': "For what did you pledge to the Messenger of Allah (ﷺ) on the Day of Al-Hudaibiyyah?" He said: "For death."

This Hadith is Hasan Sahih.

Jami` at-Tirmidhi Book 21, Hadith 54 Next Hadith → "We did not pledge to the Messenger of Allah (ﷺ) for death, but only that we would not flee."

This Hadith is Hasan Sahih, meaning both of the Ahadith are Sahih. Some of his Companions pledged to him for death, they said only: "We will not leave from in front of you as long as we are not killed." While others pledged him by saying: "We will not flee."
