A vetala (Sanskrit: वेताल vetāla) is a revenant in Hindu mythology, usually defined as a knowledgeable (fortune telling) paranormal entity said to be dwelling at charnel grounds. The vetala is comparable to the vampires of Western mythology. Reanimated corpses are used as vehicles by the spirits for movement, the corpse no longer decays while it is inhabited by a vetala. A vetala may possess and also leave a dead body at will.
Ababil (Arabic: أبابيل, romanized: abābīl) means a flock of birds. It refers to the miraculous birds in Islamic belief mentioned in Sura 105 of the Quran that protected the Kaaba in Mecca from the Aksumite elephant army of Abraha, then self-styled governor of Himyar, by dropping small clay stones on them as they approached. In the translation of sahih international, the phrase "tayran abābīl(a)"(طَيْرًا أَبَابِيلَ) is translated as "Birds in flocks" that is mentioned in the verse 105:3. The event is said to have occurred in 570, the year that the Islamic prophet Muhammad was born.
