[Machine] The Prophet ﷺ used to say, "There is no regret in this world except in three situations: a man who had a watering hole and a garden where he used to irrigate his land, but when his land became very thirsty and its fruits died, his watering hole also dried up. He feels regret over his watering hole because he couldn't find a similar one, and he feels regret over his land's fruits because they spoiled before he could find a solution. And a man who had a well-trained horse and encountered a group of disbelievers, and when some of them approached him, the enemies of Allah were defeated. The man raced ahead on his horse, but when he realized he couldn't catch up, his horse got injured and was left behind. He feels regret over his horse because he can't find another like it, and he feels regret over missing the victory that he was close to. And a man who is married to a woman whom he is pleased with in her beauty and religion, but she passes away and he is left without her. He feels regret over his wife, fearing he will never find anyone like her, and he feels regret over his child, fearing that his inheritance will be destroyed before he finds a nursing mother for him." And he said, "And these are some of the greatest sources of regret."  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ لَيْسَ فِي الدُّنْيَا حَسْرَةٌ إِلَّا فِي ثَلَاثٍ رَجُلٍ كَانَ لَهُ سَقْيٌ وَلَهُ سَانِيَةٌ يَسْقِي عَلَيْهَا أَرْضَهُ فَلَمَّا اشْتَدَّ ظَمَأُ أَرْضِهِ وَخَرَجَ ثِمَارُهَا مَاتَتْ سَانِيَتُهُ فَيَجِدُ حَسْرَةً عَلَى سَانِيَتِهِ الَّذِي قَدْ عَلَّمَهُ السَّقْيَ أَنْ يَجِدَ مِثْلَهُ وَيَجِدُ حَسْرَةً عَلَى ثَمَرَةِ أَرْضِهِ أَنْ تَفْسَدَ قَبْلَ أَنْ يُحِيلَ لَهَا حِيلَةً وَرَجُلٍ كَانَ لَهُ فَرَسٌ جَوَادٌ فَلَقِيَ جَمْعًا مِنَ الْكُفَّارِ فَلَمَّا دَنَا بَعْضُهُمْ مِنْ بَعْضٍ انْهَزَمَ أَعْدَاءُ اللهِ فَسَبَقَ الرَّجُلُ عَلَى فَرَسِهِ فَلَمَّا كَرَبَ أَنْ يَلْحَقَ كُسِرَتْ بِهِ فَرَسُهُ وَتُرِكَ قَائِمًا عِنْدَهُ يَجِدُ حَسْرَةً عَلَى فَرَسِهِ أَنَّ لَا يَجِدَ مِثْلَهُ وَيَجِدُ حَسْرَةً عَلَى مَا فَاتَهُ مِنَ الظَّفَرِ الَّذِي كَانَ قَدْ أَشْرَفَ عَلَيْهِ وَرَجُلٍ تَحْتَهُ امْرَأَةٌ قَدْ رَضِيَ هَيْأَتَهَا وَدِينَهَا فَنَفَسَتْ غُلَامًا فَمَاتَتْ بِنَفَسِهِ فَيَجِدُ حَسْرَةً عَلَى امْرَأَتِهِ يَظُنُّ أَنَّهُ لَنْ يُصَادِفَ مِثْلَهَا وَيَجِدُ حَسْرَةً عَلَى وَلَدِهَا يَخْشَى أَنْ يَهْلِكَ ضَيْعَةً قَبْلَ أَنْ يَجِدَ لَهُ مُرْضِعَةً قَالَ «وَهَذِهِ أَكْثَرُ أُولَئِكَ الْحَسَرَاتِ»
