Qur'anScience
The Hijri year is 11 days shorter than the solar year — so the farmers’ tax date drifted away from the harvest every year. A scholar from Shiraz at Akbar’s court solved this with a solar calendar for tax matters, while also reforming revenue records, the value of coins and the madrasa curriculum. The thirty-seventh book of Tracing the Scholars of Islam tells the story of Fathullah Shirazi. “That you may know the number of years and the account [of time].”
“And We have made the night and day two signs … that you may seek bounty from your Lord and may know the number of years and the account [of time].”
