Knowing her sister's great qualities and her wise advice, she shared decisions with her brother ("tukâssimû ma'ahû siyâsèt el mulk") writes about her Hassan Husni Abd al-Wahhab.
Her brother was constantly busy facing multiple rebellions, so he charged her with governing the state and providing for the needs of the population in his absence.
