Abdullah ibn Ja’far reported: I saw the Messenger of Allah, peace and blessings be upon him, eating fresh dates with cucumbers.

Grade: Sahih (authentic) according to Muslim
Ibn al-Qayyim said, “The cucumber is cold and wet… so it is proper to use along with it whatever rectifies it and diminishes its coolness and moisture, as the Messenger of Allah did when he ate it with fresh dates. If it is eaten with dates, raisins, or honey, it will balance it out.”

عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَأْكُلُ الْقِثَّاءَ بِالرُّطَبِ
2043 صحيح مسلم كتاب الأشربة باب أكل القثاء بالرطب
قال ابن القيم الْقِثَّاءُ بَارِدٌ رَطْبٌ … فَيَنْبَغِي أَنْ يُسْتَعْمَلَ مَعَهُ مَا يُصْلِحُهُ وَيَكْسِرُ بُرُودَتَهُ وَرُطُوبَتَهُ كَمَا فَعَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذْ أَكَلَهُ بِالرُّطَبِ فَإِذَا أُكِلَ بِتَمْرٍ أَوْ زَبِيبٍ أَوْ عَسَلٍ عَدَلَهُ
