Nasai

´Bahz bin Hakim narrated from his father that his grandfather said:` "I said: 'O Prophet of Allah! I did not come to you until I had sworn more that this many times' - the number of fingers on his hands - 'that I would never come to you or follow your religion. I am a man who does not know anything except that which Allah and His Messenger teach me. I ask you by the face of Allah, the Mighty and Sublime, with what has your Lord sent you to us? He said: 'With Islam.' I said: What are the signs of Islam? He said; To say: I submit my face to Allah and give up Shirk, and, to establish the Salah and to pay Zakah. Each Muslim is sacred and inviolable to his fellow Muslim; they support one another. Allah does not accept my deed from an idolater after he becomes a Muslim, until he departs from the idolaters and joins the Muslims."'

´It was narrated from Bahz bin Hakim, from his father, from his grandfather that the Messenger of Allah (ﷺ) said:` “Allah (SWT) will not accept any good deed from a polytheist who committed polytheism after having become Muslim, until he leaves the polytheists and joins the Muslims.”
