Nasai

In this narration, "the path of Allah" refers to jihad, although dying in any righteous deed is also considered a martyr's death.

Hadith Commentary:
➊
Regarding the Battle of Badr, it is also narrated about Hazrat Umair bin Hamam (radi Allahu anhu) that he took some dates in his hand and began to eat them. Then he said:
“If I remain alive until I finish eating these dates, then this life of mine will be considered very long.” Then he leapt into the battle and attained the rank of martyrdom (shahadah).
➋
From these ahadith, it becomes evident the true and everlasting love the noble Companions (radi Allahu anhum ajma‘in) had for the religion of Islam.
They would risk their lives to attain Allah’s Paradise and were extremely eager for martyrdom (shahadah) in the cause of Allah.
(Fath al-Bari: 7/443)

Hadith Commentary: Benefits and Issues:
From this hadith, it is understood that when a person, with sincerity of intention, hastens to abandon worldly pleasures for the sake of Paradise, Allah Almighty, appreciating his sincerity, arranges for him to enter Paradise.
Who was this individual? According to Imam Khatib al-Baghdadi,
it was Umair bin Humaam al-Ansari.
However, according to Hafiz Ibn Hajar, this incident is related to the Battle of Badr,
whereas in this hadith, the Battle of Uhud is mentioned.
Therefore, it cannot be Umair, and the mention of Umair will come ahead in the narration of Anas radi Allahu anhu.

Benefit:
From this hadith, it is understood that the reward for a martyr (shaheed) is Paradise, and the noble Companions (radi Allahu anhum ajma'een) were extremely eager and desirous for Paradise. May Allah, the Exalted, grant us death in the state of martyrdom.
