The first stage of Muslim astronomy was getting past the prohibition in Ibn-i-Majah vol.5 no.3726 p.149: learning about astronomy is learning about magic. Sunan Abu Dawud vol.2 ch.1480 no.3896 p.1095 in English says the same thing, except that it uses the word "astrology".
Hatua ya kwanza ya unajimu wa Kiislamu ulianza kuvuka vizuizi vilivyokuwa katika Ibn-i-Majah juzuu ya 5 na. 3726 uk. 149: kujifunza juu ya unajimu ni kujifunza juu ya nguvu za kimiujiza (mazingaombwe). Sunan Abu Dawud juzuu ya 5 sehemu ya 1480 na. 3896 uk. 1095 katika Kiingereza yasema kitu kile kile, isipokuwa inatumia neno "astolojia."
