Mujahid (may Allah have mercy on him) said regarding Allah the Exalted’s statement:“And give its due on the day of its harvest”(__QUR_N__): When you reap the crop and the needy are present, throw some ears for them. And when you clean the crop and make a heap and the needy are present, take out some from it for them. And when you thresh and winnow the grain and the needy are present, take out some from it for them. And when you winnow the grain and measure it, then separate its zakat. And when the date clusters ripen and the needy are present, throw a few clusters and some unripe dates for them. And when you cut the dates and the needy are present, take out some from them for them. And when you gather the dates and determine their measure, then separate its zakat.
