A farmer sold some of the wheat produced by his farm to pay for some needs, is he obliged to pay Zakah on what he sold?

A 7: Zakah will be obligatory on the total sum of any plant which has ripened. The owner has to pay one tenth if his plants were irrigated for free and one twentieth if they were irrigated by machines according to what Allah (Exalted be He) says: ...pay the due thereof (its Zakât, according to Allâh’s Orders 1/10th or 1/20th) on the day of its harvest and according to what the Prophet (peace be upon him ) said: On a land watered by rain water or by natural water channels, or if the land is wet due to a nearby water channel, ‘Ushr (one-tenth) is compulsory (as Zakat); and on irrigated land, half of the ‘Ushr (one-twentieth) is compulsory (as Zakat on the yield of the land). (Agreed upon by Al-Bukhari and Muslim)Accordingly, you have to pay Zakah on the seeds you kept for the next season.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
