Also, the word falak was used by Arabs, before the time of Muhammad, to refer to the voyage of the celestial objects in the "sky dome". The people before, and in Muhammad’s time, believed in the Aristotelian/Ptolemaic model of the universe where the earth was at the center and was surrounded by 7 spherical domes.
Pia, neno falak lilitumiwa na Waarabu, kabla ya Muhammad kuzaliwa likimaanisha kuelea kwa jua, nyota na sayari kwenye "dari la anga la duara (kuba)." Watu walioishi kabla, na wakati wa Muhammad waliamini kuwa ulimwengu una mfano wa Kiaristote/Kiptolem ambamo dunia ipo katikati ikiwa imezungukwa na dari 7 za duara (kuba).
