4. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn Khalid al-Barqiy from Sa‘d ibn Sa‘d al- Ash’ariy who has said the following: “I once asked abu al-Hassan, al-Rida’ , about a man whose accounting time comes three times in a year. Can he delay to make them all at one time? He (the Imam) said, ‘Whenever it comes he must pay Zakat.’ I then asked, ‘When it is the time to pay Zakat of wheat, barley, dates and raisins? He (the Imam) said, ‘It is when he cuts and estimates.’”
