Sahih al-Bukhari · Book 24: Obligatory Charity Tax (Zakat) · Whoever sold his fruits, trees, land or crops and gave Zakat from some other property
Narrated Jabir bin `Abdullah:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، حَدَّثَنِي اللَّيْثُ ، حَدَّثَنِي خَالِدُ بْنُ يَزِيدَ ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ. نَهَى النَّبِيُّ صلى الله عليه وسلم عَنْ بَيْعِ الثِّمَارِ حَتَّى يَبْدُوَ صَلاَحُهَا.
The Prophet (ﷺ) had forbidden the sale of fruits till they were ripe (free from blight).
