Abu Buraida said:

“Salman al-Farisi brought Allah’s Messenger (ﷺ), when he reached Medina, a table with ripe dates upon it, and he placed it in front of Allah’s Messenger (ﷺ), so he said: ‘O Salman, what is this?’ He replied: A charitable gift for you and for your Companions’ ‘Take it away,’ said the Prophet, ‘for we will not eat a charitable gift.’ He therefore took it away. Then he came the next day with the like of it, and placed it in front of Allah’s Messenger (ﷺ), who said: ‘What is this, O Salman?’ He replied: ‘A present for you,’ so Allah’s Messenger (ﷺ) said to his Companions: ‘Spread out!’ Then Salman looked at the Seal on the back of Allah’s Messenger (ﷺ), so he believed in him. He was a slave of the Jews, however, so Allah’s Messenger (ﷺ) purchased his freedom at such-and-such a price of silver coin, on condition that he [the Prophet] would plant date palms for them, and Salman would work on them until they bore edible fruit. Allah’s Messenger (ﷺ) then planted the date palms, apart from one date palm that 'Umar planted. The date palms then bore their annual crop, but one date palm did not bear fruit, so Allah’s Messenger said (ﷺ): ‘What is the matter with this date palm?’ 'Umar said: ‘O Messenger of Allah, I planted it!’ Allah’s Messenger (ﷺ) therefore uprooted it and replanted it, so it bore its annual crop."

حَدَّثَنَا أَبُو عَمَّارٍ الْحُسَيْنُ بْنُ حُرَيْثٍ الْخُزَاعِيُّ، قَالَ‏:‏ حَدَّثَنَا عَلِيُّ بْنُ حُسَيْنِ بْنِ وَاقِدٍ، حَدَّثَنِي أَبِي، قَالَ‏:‏ حَدَّثَنِي عَبْدُ اللهِ بْنُ بُرَيْدَةَ، قَالَ‏:‏ سَمِعْتُ أَبِي بُرَيْدَةَ، يَقُولُ‏:‏ جَاءَ سَلْمَانُ الْفَارِسِيُّ إِلَى رَسُولِ اللهِ صلى الله عليه وسلم، حِينَ قَدِمَ الْمَدِينَةَ بِمَائِدَةٍ عَلَيْهَا رُطَبٌ، فَوَضَعَهَا بَيْنَ يَدَيْ رَسُولِ اللهِ صلى الله عليه وسلم، فَقَالَ‏:‏ يَا سَلْمَانُ مَا هَذَا‏؟‏ فَقَالَ‏:‏ صَدَقَةٌ عَلَيْكَ، وَعَلَى أَصْحَابِكَ، فَقَالَ‏:‏ ارْفَعْهَا، فَإِنَّا لا نَأْكُلُ الصَّدَقَةَ، قَالَ‏:‏ فَرَفَعَهَا، فَجَاءَ الْغَدَ بِمِثْلِهِ، فَوَضَعَهُ بَيْنَ يَدَيْ رَسُولِ اللهِ صلى الله عليه وسلم، فَقَالَ‏:‏ مَا هَذَا يَا سَلْمَانُ‏؟‏ فَقَالَ‏:‏ هَدِيَّةٌ لَكَ، فَقَالَ رَسُولُ اللهِ صلى الله عليه وسلم لأَصْحَابِهِ‏:‏ ابْسُطُوا ثُمَّ نَظَرَ إِلَى الْخَاتَمِ عَلَى ظَهْرِ رَسُولِ اللهِ صلى الله عليه وسلم، فَآمَنَ بِهِ، وَكَانَ لِلْيَهُودِ فَاشْتَرَاهُ رَسُولُ اللهِ صلى الله عليه وسلم، بِكَذَا وَكَذَا دِرْهَمًا عَلَى أَنْ يَغْرِسَ لَهُمْ نَخْلا، فَيَعْمَلَ سَلْمَانُ فِيهِ، حَتَّى تُطْعِمَ، فَغَرَسَ رَسُولُ اللهِ صلى الله عليه وسلم، النَّخلَ إِلا نَخْلَةً وَاحِدَةً، غَرَسَهَا عُمَرُ فَحَمَلَتِ النَّخْلُ مِنْ عَامِهَا، وَلَمْ تَحْمِلْ نَخْلَةٌ، فَقَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ مَا شَأْنُ هَذِهِ النَّخْلَةِ‏؟‏ فَقَالَ عُمَرُ‏:‏ يَا رَسُولَ اللهِ، أَنَا غَرَسْتُهَا، فَنَزَعَهَا رَسُولُ اللهِ صلى الله عليه وسلم، فَغَرَسَهَا فَحَمَلَتْ مِنْ عَامِهَا‏.‏
