A miracle and salvation for the Jews of Egypt on the 27th of Adar 5284, and they accepted upon themselves and their descendants a day of feasting and rejoicing [(Shevet Yehudah 55b and Tzedah LaDerech, Part 2). And see Sha'arei Kedusha 64b and as follows:] HaRav Rabbi Shmuel Tziraliyo, son-in-law of HaRav Avudhav, has a true tradition that when Sultan Suleiman conquered Egypt in 1272 after the Destruction [(this does not match Tzedah LaDerech which wrote 5284)], he commanded one of his officers to be viceroy in that kingdom.

The viceroy rebelled against the king and issued an order to the Jews that within eight days they must bring him a great sum of money that was impossible for them, on pain of sword and death. The Jews began fasting and praying. This wicked man brought about 300 youths from twelve years old and younger and shut himself up with them to fast and pray with a loud voice in the great synagogue of Egypt, and he continued his prayer until the afternoon.

HaShem answered his voice, for before he left, news reached him that the viceroy had been killed, and this was on the 27th of Adar. Some say he prayed so intensely that he almost spoke against Heaven, which is why his descendant came forth with much light. From this event a Megillah was made [end of quotation, (and see HaRav Rabbi Yosef HaKohen 5290)]. In that year, great and fearsome heavenly signs were seen, and in the land of Verona and other places, flocks of crows gathered in great numbers, thousands and tens of thousands, in three provinces, and they fought each other in the air in broad daylight, killing each other without number.

All this was a sign of the wars of Christians against Christians [(Tzedah LaDerech, Part 2)].
