I think in our culture women are raised to practice religion more…like you see more women in a household doing namaz and roza as compared to guys…you see moms getting after their daughters to read namaz and Quran and hardly care about what the son’s are doing…OK this may be wrong and very general and biased, but I have seen that in many families, so as a result, women seem to do more in terms of ibadat, etc. Women are also more caring by nature so they do all these little little things more…
Having said that, women after all their ibadaat, gossip more and backbite more hence losing all their credit points and balancing out with the men
