Appears 3 times in the Quran.
19:23 فَأَجَآءَهَا ٱلْمَخَاضُ إِلَىٰ جِذْعِ ٱلنَّخْلَةِ قَالَتْ يَٰلَيْتَنِى مِتُّ قَبْلَ هَٰذَا وَكُنتُ نَسْيًا مَّنسِيًّا
And the throes (of childbirth) compelled her to betake herself to the trunk of a palm tree. She said: Oh, would that I had died before this, and had been a thing quite forgotten!
And shake towards you the trunk of the palmtree, it will drop on you fresh ripe dates:
20:71 قَالَ ءَامَنتُمْ لَهُۥ قَبْلَ أَنْ ءَاذَنَ لَكُمْ إِنَّهُۥ لَكَبِيرُكُمُ ٱلَّذِى عَلَّمَكُمُ ٱلسِّحْرَ فَلَأُقَطِّعَنَّ أَيْدِيَكُمْ وَأَرْجُلَكُم مِّنْ خِلَٰفٍ وَلَأُصَلِّبَنَّكُمْ فِى جُذُوعِ ٱلنَّخْلِ وَلَتَعْلَمُنَّ أَيُّنَآ أَشَدُّ عَذَابًا وَأَبْقَىٰ
(Firon) said: You believe in him before I give you leave; most surely he is the chief of you who taught you enchantment, therefore I will certainly cut off your hands and your feet on opposite sides, and I will certainly crucify you on the trunks of the palm trees, and certainly you will come to know which of us is the more severe and the more abiding in chastising.
