Who is known as the "Martyr of the Garden"?

No Companion by the title "Shahid al-Hadiqa" (Martyr of the Garden) has been found. Perhaps the questioner is referring to the Companion Al-Bara' ibn Malik, who opened the "Garden of Death" on the day of fighting Musaylimah. On that day, he sustained severe injuries, but he was not martyred then; rather, he lived and participated in other wars, and was martyred on the day of the conquest of Tustar in the year 20 AH, during the caliphate of Umar.
