[Machine] The Messenger of Allah ﷺ said that when the sky, palm tree, and mountain give water, it is a tenth. And when it is given by means of surface water, then it is half of the tenth. And this only applies to dates, wheat, and grains. As for cucumber, watermelon, pomegranate, and squash, the Messenger of Allah ﷺ pardoned them. This was narrated by Yahya ibn al-Mughira from Ibn Nafi' who said that the Messenger of Allah ﷺ pardoned cucumber and green vegetables. Abu Bakr ibn al-Harith al-Faqih informed us, and Ali ibn Umar al-Hafiz narrated to us, and Ali ibn Ahmad al-Azraq in Egypt narrated to us, and Muhammad ibn Muhammad ibn al-Naffah narrated to us, and Yahya ibn al-Mughira mentioned it with addition.
