The Shar’i Month

What does “decrease” or “fall short” mean [in the Hadeeth: “The two months of Eid do not decrease”]?

A month can be either longer or shorter. The Shariat has taken both into consideration. In some calculations [i.e. the calculations of other nations and some other civilizations] 28, 31, 32 [and even 35 days] are considered. However, the Shariat has only recognized 29 or 30 days because the sighting of the new moon (Hilaal) is recognized only on completion of these two days. There is no third option.

Other calculators have plotted the solar calendar, but the Shariat has rejected it [for the purpose of plotting the Islamic months]. The solar calculation, in view of it not being perceivable and not being apparent, is difficult. We cannot see the sun moving into the 365 or so positions of its orbit and hence the solar year’s calculation is extremely hard for an ordinary person [to follow. The need for external mediums, such as calendars, clocks, etc. to keep track of the changing months in the solar calculation is testimony to this fact].

In contrast, the lunar calculation is plotted with the aid of the moon which can be seen waxing and waning and cannot be refuted by anyone having sight. Its calculation is, therefore, easy and within the means of ordinary folk [for all times and all over the earth]. Furthermore, the knowledge or science which is accessible to the masses is obviously easy.
