Al-Malik Al-Afdal
(Died in 778 A.H/ 1377 A.D)
Profile:
Abbas Al-Rasuli is an encyclopedia who combined between theoretical and practical science, perhaps the need of the authority and leadership gave him hope to write in various fields by responding to the need and excelling in his offer.
In his book “Bughyat Al-Fallahin”, there is a chapter entitled “the fifth chapter in times of agriculture and what needs to be achieved”. He divided the chapter into three sections and said “know that the most important thing one needs to know is the times of sowing and planting in order to aim for what is good for it, and to avoid what spoils it”.
He expanded his research on the “seasons of the year” and mentioned the schools of thought in that regard, then suggested “the seasons do not have a known limit, rather they differ in the country according to the difference in their circles of latitude”.
He distinguished between seasons of the year for astrologers, he said: “they are the seasons of the year for farmers”.
A careful reading of this analysis and other Islamic and human heritage requires a review of the typical solar seasons in the Gregorian date, in addition to reconsidering the globalization of colonial measures and standards, that do not necessarily serve the colonized countries, because they do not serve their goal and their purpose in all aspects of life using imported standards and measures.
