Hazrat Ibn Jurayj says that Abu Zubair told me that he heard from Hazrat Jabir that there is 'ushr in it.

Hazrat Ibn Jurayj says that I asked Hazrat Ata: What is the ruling regarding the date palm (orchard) that is irrigated without effort, or crops and grains that are irrigated by rainwater? He replied: Ushr (one-tenth). I asked: What is the ruling if dates, grapes, and grains are irrigated by running water? He replied: Ushr (one-tenth). I asked: What is the ruling for land that is irrigated by buckets and camels? He replied: Half of Ushr (one-twentieth).

Hazrat Ibn Jurayj states that Abu Zubair informed me that Hazrat Jabir bin Abdullah (may Allah be pleased with him) said that half of a tenth is due.

It is narrated from Hazrat Muammar that Hazrat Imam Zuhri does not specify any fixed amount for fruits. He says that it is either ‘ushr’ or half ‘ushr’.

It is also narrated in the same way from Hazrat Mujahid.

Hazrat Muammar narrates that Hazrat Umar bin Abdul Aziz had written the same (order) to the people of Yemen.

Hasan says that when wheat, barley, dates, and grapes reach five wasq, and five wasq is three hundred sa’, then if they are irrigated by oneself, half of a tenth (half ‘ushr) is due on them, and if they are irrigated by rainwater or spring water, then a tenth (‘ushr) is due on them.

It is narrated from Hazrat Nafi’ that Hazrat Abdullah used to give the verdict regarding the zakat of fruits and crops that for that which is irrigated by river or spring water, or by rainwater, or by means of a camel, the zakat is ‘ushr, that is, one out of every ten. And for that which is irrigated by means of a pond (by lifting and carrying water), the zakat is half of ‘ushr, that is, one out of every twenty.
