Executive member of the union Noor Nongrum said women could offer prayers five times on Fridays.
"Women should be treated on par with men. We have tried it through this endeavour and we are proud."
While dismissing the notion that Muslim women are not allowed inside the mosque, he said neither in the Quran nor in the Hadish is it written that women can't enter the mosque.
Men and women enjoy equal rights everywhere in the world and we tried to bridge the gap between the sexes in the region, Nongrum said.
The women who offered prayers appeared elated and acknowledged the 'right'. However, the mosque authorities had laid down a purdah to separate the men from the women while offering prayers.
