Salman Farsi reported,

I was among the sons of the Persian cavalry commanders. He then mentioned the hadith, saying, I traveled, with the land lifting me up at times and lowering me at others, until I passed by a group of Bedouins who took me as a slave and sold me. Eventually a woman bought me. I heard them mentioning the Prophet ﷺ, and food was scarce at the time.I said to her, "Grant me a day off."She replied, "Yes."So I went out, gathered firewood, sold it, and prepared some food. I brought it to the Prophet ﷺ and placed it before him.He asked, "What is this?"I answered, "Charity."He told his companions, "Eat," but he himself did not eat. I said to myself, this is one of his signs.Then I remained as long as Allah willed, after which I said to my mistress, "Grant me a day off."She replied, "Yes."So I went out, gathered more firewood than before, prepared some food, and brought it to him while he was sitting among his companions. I placed it before him.He asked, "What is this?"I answered, "A gift."He extended his hand and said to his companions, "Take, in the name of Allah." I stood behind him, and he laid aside his cloak, and there was the seal of prophethood.I said, "I bear witness that you are the Messenger of Allah."He asked, "How is that?"So I told him about the man and said, "Will he enter Paradise, Messenger of Allah? He told me that you are a prophet."He replied, "None will enter Paradise except a Muslim soul."I said, "Messenger of Allah, he informed me that you are a prophet. Will he enter Paradise?"He replied, "None will enter Paradise except a Muslim soul."

عن سلمان الفارسي قال

كنت من أبناء أساورة فارس فذكر الحديث قال فانطلقت ترفعني أرض وتخفضني أخرى حتى مررت على قوم من الأعراب فاستعبدوني فباعوني حتى اشترتني امرأة فسمعتهم يذكرون النبي ﷺ وكان العيش عزيزا فقلت لها هبي لي يوما فقالت نعم فانطلقت فاحتطبت حطبا فبعته فصنعت طعاما فأتيت به النبي ﷺ فوضعته بين يديه فقال ما هذا فقلت صدقة فقال لأصحابه كلوا ولم يأكل قلت هذه من علاماته ثم مكثت ما شاء الله أن أمكث فقلت لمولاتي هبي لي يوما قالت نعم فانطلقت فاحتطبت حطبا بأكثر من ذلك فصنعت طعاما فأتيته به وهو جالس بين أصحابه فوضعته بين يديه فقال ما هذا قلت هدية فوضع يده وقال لأصحابه خذوا بسم الله وقمت خلفه فوضع رداءه فإذا خاتم النبوة فقلت أشهد أنك رسول الله فقال وما ذاك فحدثته عن الرجل وقلت أيدخل الجنة يا رسول الله فإنه حدثني أنك نبي فقال لن يدخل الجنة إلا نفس مسلمة فقلت يا رسول الله إنه أخبرني أنك نبي أيدخل الجنة قال لن يدخل الجنة إلا نفس مسلمة
