Surah 4. An-Nisaa', Ayah 32

Men and women have gifts from Allah-some greater than others. They seem unequal, but we are assured that Allah has allotted them by a scheme by which people receive what they earn. If this does not appear clear in our sight, let us remember that we have no full knowledge but Allah has. We must not be jealous if other people have more than we have-in wealth or position or strength or honour or talent or happiness. Probably things are equalized in the aggregate or in the long run, or equated to needs and merits on a scale which we cannot appraise. If we want more, instead of being jealous or covetous, we should pray to Allah and place before Him our needs. Though He knows all, and has no need of our prayer, our prayer may reveal to ourselves our shortcomings and enable us to deserve more of Allah's bounty or make ourselves fit for it.
