Musnad Ahmad 597:0

Narrated to us by Yahya ibn Sa’id, from Shu’bah, who said: Narrated to us ‘Amr ibn Murrah, who said: I heard Murrah al-Hamadani narrating from ‘Amr ibn Murrah al-Juhani, that a man came to the Prophet (ﷺ) and said: "O Messenger of Allah, if I bear witness that there is no god but Allah and that you are the Messenger of Allah, and I pray the five prayers, and I give the Zakat of my wealth, and I fast the month of Ramadan, then who am I among?" The Prophet (ﷺ) said: "Among the truthful and the martyrs."
