Answer: Kufw in occupation means that the man must not have such an occupation that is conceived as being socially inferior and could make the woman’s guardians feel disgraced. Ṣadr-ush-Sharī’aĥ, Badr-uṭ-Ṭarīqaĥ, ‘Allāmaĥ Maulānā Muftī Muhammad Amjad ‘Alī A’ẓamī عَـلَيْهِ رَحْـمَةُ الـلّٰـهِ الۡـقَـوِی wrote on page 55, part 7 of Maktaba-tul-Madīnaĥ’s version of Baĥār-e-Sharī’at: Men whose occupations are considered embarrassing are not Kufw for women whose family occupations are respectable. For example, shoe-makers (cobblers), tanners, horse-keepers, and shepherds are not Kufw for cloth-merchants, perfume-sellers, or businessmen. If he does not make shoes himself, in fact, he owns a factory and employs other people to do this work for him, or if he is a shop-owner who buys and sells ready-made shoes, then he is Kufw for a businessman etc. The same applies to other occupations too.
