Hijri Calendar and the Seasons

Answered according to Shafi'i Fiqh by

Question: Was the Hijri calendar originally in synchrony with the four seasons? Is Ramadan supposed to be fasted in the Spring?


Wa alaykum assalam wa rahmatullahi wa barakatuh,

Dear questioner,

Thank you for your important question.

While there is evidence that certain pre-Islamic Arab communities adjusted and aligned the lunar calendar with the four seasons utilizing a system of intercalation, it is not fair to state that all pre-Islamic Arab communities did that.

Furthermore, to assume that this practice happened during the Medinan period of the  Messenger of Allah (peace and blessings be upon him) when all the details of Islamic law and Islamic rituals were established is incorrect. This is clearly evinced by comparing clear and well-documented historical dates such as the Covenant with the Christians of the World and the Covenant with the Jews of Khaybar and Maqna with Jewish and Christian calendars.

We have to understand that Allah has preserved this religion. Allah has made sure that scholars have been there to preserve the religion in its pristine form and solve new confusions that the Muslims face in every generation. When all the scholars of jurisprudence agree that the lunar calendar is the basis of the Islamic calendar, despite their very desperate and variegated research methods and conclusions, we know as a fact that this is what Allah wants us to do. Revisionist ideas on issues that are agreed upon are not welcome.

The Messenger of Allah (peace and blessings be upon him) said, ‘There will always be a group of my nation who will keep to the way of Allah unharmed by those who try to trick them or work against them until Allah’s command comes while they are in power.’ (Muslim)

Revisionists posit that the Sunna was lost a long time ago and that everyone has been wrong for centuries. This is completely against the teachings of the Qur’an and Sunna.
