حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا مُحَمَّدُ بْنُ سَعِيدٍ، حَدَّثَنَا شَرِيكٌ، عَنْ سِمَاكٍ، عَنْ أَبِي ظَبْيَانَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ بِمَ أَعْرِفُ أَنَّكَ نَبِيٌّ قَالَ " إِنْ دَعَوْتُ هَذَا الْعِذْقَ مِنْ هَذِهِ النَّخْلَةِ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ " . فَدَعَاهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَجَعَلَ يَنْزِلُ مِنَ النَّخْلَةِ حَتَّى سَقَطَ إِلَى النَّبِيِّ صلى الله عليه وسلم ثُمَّ قَالَ " ارْجِعْ " . فَعَادَ فَأَسْلَمَ الأَعْرَابِيُّ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ صَحِيحٌ .
Narrated Ibn 'Abbas:"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
