Abu Hurairah reported,

He used to say, "Tell me about a man who entered Paradise without ever having performed a single prayer."When people did not recognize who he meant, they would ask him, "Who is he?"He would reply, "Usayrim of Banu Abd al-Ashhal, Amr bin Thabit bin Waqsh."Husayn said, I asked Mahmud bin Labeed, "What was the story of Usayrim?"He said, He had refused to accept Islam along with his people. But on the day of Uhud, when the Messenger of Allah ﷺ set out for Uhud, Islam suddenly appealed to him, so he embraced it. He took his sword, set off, and reached the army, mingling among the ranks. He fought until his wounds disabled him.While Some men of Banu Abd al-Ashhal were searching for their dead on the battlefield, they came upon him. They said, "By Allah, this is Usayrim! What brought him here? We left him still rejecting this religion. Ask him what brought him."They said, "What brought you here, Amr? Was it concern for your people, or a desire for Islam?"He answered, "Rather, a desire for Islam. I believed in Allah and His Messenger and accepted Islam. Then I took my sword and went out with the Messenger of Allah ﷺ and fought until what has befallen me befell me."He died in their hands shortly afterward. They mentioned him to the Messenger of Allah ﷺ, and he said, "He is indeed among the people of Paradise."

عن أبي هريرة قال

كان يقول: حدثوني عن رجل دخل الجنة لم يصل قط، فإذا لم يعرفه الناس سألوه: من هو؟ فيقول: أصيرم بني عبد الأشهل عمرو بن ثابت بن وقش. قال الحصين: فقلت لمحمود بن لبيد: كيف كان شأن الأصيرم؟ قال: كان يأبى الإسلام على قومه، فلما كان يوم أحد وخرج رسول الله ﷺ إلى أحد، بدا له الإسلام فأسلم، فأخذ سيفه فغدا حتى أتى القوم فدخل في عرض الناس، فقاتل حتى أثبتته الجراحة، قال: فبينما رجال بني عبد الأشهل يلتمسون قتلاهم في المعركة إذا هم به، فقالوا: إنه للأصيرم، وما جاء؟ لقد تركناه وإنه لمنكر لهذا الحديث، فاسألوه ما جاء به؟ قالوا: ما جاء بك يا عمرو، أحدبا على قومك أو رغبة في الإسلام؟ قال: بل رغبة في الإسلام، آمنت بالله ورسوله وأسلمت، ثم أخذت سيفي فغدوت مع رسول الله ﷺ فقاتلت حتى أصابني ما أصابني، قال: ثم لم يلبث أن مات في أيديهم، فذكروه لرسول الله ﷺ فقال: إنه لمن أهل الجنة.
