I heard the Messenger of Allah ﷺ say, "Whoever wishes to look at a martyr walking on the face of the earth, let him look at Talha bin Ubaydullah."
حدثنا قتيبة حدثنا صالح بن موسى الطلحي من ولد طلحة بن عبيد الله عن الصلت بن دينار عن أبي نضرة قال
سمعت رسول الله ﷺ يقول من سره أن ينظر إلى شهيد يمشي على وجه الأرض فلينظر إلى طلحة بن عبيد الله
[Daif] Ibn Majah also narrated it, no. 125, from the hadith of Salt bin Dinar, transmitted the same way, and he is discarded (matruk) as Ahmad and others have said. Salih bin Musa is similar, refer to Tahdhib, and I did not find for it any sahih or hasan chain.
