"A Bedouin came to the Messenger of Allah ﷺ and said: 'How shall I know that you are a Prophet?' He said: 'If I were to call this date cluster from this palm tree, would you bear witness that I am the Messenger of Allah?' So the Messenger of Allah ﷺ called it and they started to fall from the tree, until they fell towards the Prophet ﷺ, then he said: 'Go back,' and it went back. So the Bedouin accepted Islam."  

جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ بِمَ أَعْرِفُ أَنَّكَ نَبِيٌّ قَالَ إِنْ دَعَوْتُ هَذَا الْعِذْقَ مِنْ هَذِهِ النَّخْلَةِ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ فَدَعَاهُ رَسُولُ اللَّهِ ﷺ فَجَعَلَ يَنْزِلُ مِنَ النَّخْلَةِ حَتَّى سَقَطَ إِلَى النَّبِيِّ ﷺ ثُمَّ قَالَ ارْجِعْ فَعَادَ فَأَسْلَمَ الأَعْرَابِيُّ  

[Machine] he following is the translation of the passage into English:

An Arab man came to the Prophet ﷺ and said, "How can I know that you are the Messenger of Allah?" The Prophet ﷺ said, "If I call this date palm tree and it bears witness that I am the Messenger of Allah, would you believe?" The man said, "Yes." Then, the Prophet ﷺ called the date palm tree and it descended from the tree until it fell on the ground. The man was astonished and continued to follow the Prophet ﷺ until they reached a certain place. Then, the Prophet ﷺ told him to go back, and the man returned to his place and said, "I bear witness that you are the Messenger of Allah and I believe."  

جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ فَقَالَ بِمَ أَعْرِفُ أَنَّكَ رَسُولُ اللهِ؟ قَالَ «إِنْ دَعَوْتُ هَذَا الْعِذْقَ مِنْ هَذِهِ النَّخْلَةِ أَتَشْهَدُ أَنِّي رَسُولُ اللهِ؟» قَالَ نَعَمْ فَجَاءَ الْعِذْقُ يَنْزِلُ مِنَ النَّخْلَةِ حَتَّى سَقَطَ فِي الْأَرْضِ فَجَعَلَ يَنْقُرُ حَتَّى أَتَى النَّبِيَّ ﷺ ثُمَّ قَالَ لَهُ «ارْجِعْ» فَرَجَعَ حَتَّى عَادَ إِلَى مَكَانِهِ فَقَالَ أَشْهَدُ أَنَّكَ رَسُولُ اللهِ وَآمَنَ
