“Therefore the righteous women are devoutly obedient (to Allaah and to their husbands), and guard in the husband’s absence what Allaah orders them to guard (e.g. their chastity and their husband’s property)” [al-Nisa’ 4:34].
Shaykh ‘Abd al-Rahmaan al-Sa’di (may Allaah have mercy on him) said:
“Therefore the righteous women are devoutly obedient” means: obedient to Allaah, may He be exalted.
“guard in the husband’s absence” means: they are obedient to their husbands and even in their absence they guard themselves and their husband’s wealth, seeking the help of Allaah in that, because no one can do that by himself or herself, for the self is inclined towards evil, but the one who puts his trust in Allaah, He will suffice him and help him in his religious and worldly affairs.
