HE DID A LITTLE WORK BUT EARNED A GREAT REWARD

He is a companion who neither made a single Sujūd nor Sadaqah but became a dweller of Jannah, he came to the Prophet on the day of Uhud wanting to fight alongside the Messenger of Allāh before he accepted Islām, he asked the Prophet (Sallallahu alayhi was Salaam):

Should I fight first then accept Islām?
The Messenger of Allāh replied: “Embrace Islām first and then fight” so he embraced Islām, fought and martyred, Allāhu Akbar!

The Messenger of Allāh (sallallahu alayhi was Salaam) said about him:
” He worked a little(after embracing Islām) but earned a great reward”

He is no other Ṣahābiy than
‘AMR BN THĀBIT AL UṢAYRIM(may Allāh be pleased with him)

Al-Barah Bn ‘Āzib(radiyallahu ‘Anhu) narrated

A man whose face was covered with an iron mask (i.e. clad in armor) came to the Prophet and said, “O Allah’s Apostle! Shall I fight or embrace Islam first? “The Prophet said, “Embrace Islam first and then fight.” So he embraced Islam, and was martyred. Allah’s Apostle said, A Little work, but a great reward. “(He did very little (after embracing Islam), but he will be rewarded in abundance).
