The Messenger of Allah ﷺ set out for Badr. When he reached Harrat-ul-Wabara (a place four miles from Medina) a man met him who was known for his valour and courage. The Companions of the Messenger of Allah ﷺ were pleased to see him. He said: I have come so that I may follow you and get a share from the booty. The Messenger of Allah ﷺ said to him: Do you believe in Allah and His Apostle? He said: No. The Messenger of Allah ﷺ said: Go back, I will not seek help from a Mushrik (polytheist). He went on until we reached Shajara, where the man met him again. He asked him the same question again and the man gave him the same answer. He said: Go back. Im will not seek help from a Mushrik. The man returned and overtook him at Baida'? He asked him as he had asked previously: Do you believe in Allah and His Apostle? The man said: Yes. The Messenger of Allah ﷺ said to him: Then come along with us. (Using translation from Muslim 1817)   

خَرَجَ رَسُولُ اللهِ ﷺ قَبْلَ بَدْرٍ فَلَمَّا كَانَ بِحَرَّةِ الْوَبَرَةِ أَدْرَكَهُ رَجُلٌ قَدْ كَانَ يُذْكَرُ مِنْهُ جُرْأَةٌ وَنَجْدَةٌ فَفَرِحَ أَصْحَابُ رَسُولِ اللهِ ﷺ حِينَ رَأَوْهُ فَلَمَّا أَدْرَكَهُ قَالَ يَا مُحَمَّدُ جِئْتُ لِأَتَّبِعَكَ وَأُصِيبَ مَعَكَ؟ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «أَتُؤْمِنُ بِاللهِ وَرَسُولِهِ؟» قَالَ لَا قَالَ «فَارْجِعْ فَلَنْ نَسْتَعِينَ بِمُشْرِكٍ» ثُمَّ مَضَى حَتَّى إِذَا كُنَّا بِالشَّجَرَةِ أَدْرَكَهُ فَقَالَ لَهُ كَمَا قَالَ أَوَّلَ مَرَّةٍ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ كَمَا قَالَ أَوَّلَ مَرَّةٍ قَالَ لَا قَالَ «فَارْجِعْ فَلَنْ أَسْتَعِينَ بِمُشْرِكٍ» فَرَجَعَ ثُمَّ أَدْرَكَهُ بِالْبَيْدَاءِ فَقَالَ لَهُ كَمَا قَالَ أَوَّلَ مَرَّةً فَقَالَ لَهُ النَّبِيُّ ﷺ «تُؤْمِنُ بِاللهِ وَرَسُولِهِ؟» قَالَ نَعَمْ قَالَ «فَانْطَلِقْ»  

[Machine] The Messenger of Allah ﷺ set out towards Badr. When he reached the area of Wabarah, he was intercepted by a man known for his bravery and assistance. The companions of the Messenger of Allah ﷺ were delighted to see him. When the man caught up with him, he said, "O Messenger of Allah, I have come to follow you and to be with you in battle." The Messenger of Allah ﷺ asked him, "Do you believe in Allah and His Messenger?" He replied, "No." The Messenger of Allah ﷺ said, "Then go back, for I will not seek assistance from a polytheist." The man left. Later, when the man caught up with him near a tree, he said the same thing. The Prophet ﷺ responded in the same way, telling him to go back since he did not believe in Allah and His Messenger. The man returned. Finally, when the man caught up with him in the open desert, he said the same thing. The Prophet ﷺ asked him, "Do you believe in Allah and His Messenger?" He answered, "Yes." The Prophet ﷺ then said, "Then go ahead."
