Ibn Jubayr started writing his observations 20 days after his travel. He was documenting it according to the week days and according to the Arabic and French months following the personal memorandum style. This was in contrast of Ibn Battuta (1377) who, after years of his travel, mentioned the details of his travel to Muhammad Ibn Juzayy, the writer of sultan Marinid Sultanate Abu Inan Faris, who wrote it in his own style too.
