Golden Advises for Muslim Wives and their Roles

i) Solat/ namaz on time (reason being; ONE, try not to delay solat/ namaz fearing that when we delay one until the next fardhz namaz time, we will have our menses, and with that, we still need to qada' our solat/ namaz, SECONDLY, when you received an unexpected guests at home and that can causes you to delay your namaz, THIRDLY, for pregnant Muslimah, fearing that you will give birth before you could even pray your namaz, and FOURTH, not the least of importance, fearing death will invite you while you're in the state of delaying your namaz/ solat)
ii) Istiqamah (attend taleem and give ta'lum, meaning, to attend ilm gathering for women and teaches/ share what you've learned from such gathering; recite Qur'an often and reflect on one's good deeds and bad ones too)
iii) Much zikrullah as women tend to wonder and think about matters of no weigh and importance for the goodness of her Deen in her mind.
iv) Educate and nurture their children according to the Sunnah of the Prophet sallallahu alaihi wasallam.
v) Live in simplicity; Not being spendrift, getting things according to our needs and not wants.
vi) Tableegh; spread da'wah and be a walking da'wah.
