Investama Mandiri genuine, Coventry-Bogor; KPP PMA TWO, Kalibata, South Jakarta; KPP Primary Kebayoran I, Patra Jasa, Central Jakarta; PT.Gunung Agung, Jakarta Centre; Muslim Family Citi Bank, South Jakarta, and KPP PMB, K-Link Tower, Central Jakarta. Results about the perception and understanding of the Muslimah workers in six offices or companies indicated that their perception and understanding of fiqih thaharah and prayers can be said to be good. But regrettably there are two issues related to the knowledge of fiqih thaharah are not understood by the respondents, namely: (1) When the respondent has dried from the menstruation, while they are still working in the office, because it is not available in the office bathroom, they do not pray with unwashed reasons, because there is no bathroom in which to bathe menstruation.
