Is it obligatory for a Muslim to learn and memorize the sciences of the Quran and the Prophetic biography in detail, and specific hadiths such as the descriptions of the Dajjal and the Mahdi and the details of the Day of Judgment, and does this fall under the category of seeking obligatory knowledge?
