I will take them in this order.
Of the angels, unquestionably the most important are Azrael (ʿAzra’il or ʿIjrail), Michael (Mika’il), Israfel (Israfil, Ijrafil, or Serafil), and Gabriel (Jibra’il or ’Jabra’il, often corrupted into Raja Brahil). There can be no doubt that the foregoing are meant for the names of a group of four archangels, the name of Israfel corresponding to Abdiel, who generally occupies the fourth place in our own angelic hierarchy.
Their customary duties are apportioned among the four great angels as follows:—
Azrael is, as with us, the angel of death, who “carries off the lives of all creatures”; Israfel is “lord of all the different airs” in our body; Michael is the “giver of daily bread”; and Gabriel is a messenger or “bringer of news.”
Sometimes, again, a White Angel (Mala’ikat Puteh) is mentioned, e.g. as being in “charge of all things in the jungle,” but what his specific duties are in this connection does not transpire.
In an invocation addressed to the Sea-spirit, however, we find four more such angels mentioned, all of whom hold similar charges:—
Chitar Ali is the angel’s name, who is lord of the whirlpool;
Sabur Ali is the angel’s name, who is lord of the winds;
Sir Ali is the angel’s name, who is lord of the waters of the sea;
Putar Ali is the angel’s name, who is lord of the rainbow.
