Is it considered a sin to drive mahrams who wear a modest head abaya and socks, but no gloves, to the market?

Covering a woman's hands when leaving the house is obligatory according to the most preponderant opinion. It is sufficient to cover them with any covering; gloves are not necessary. A woman who leaves her house with her hands uncovered is sinful, and whoever helps her in doing so has assisted her in an evil act, based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." However, if she is able to cover her hands with any of her clothes, there is no harm in taking her to the market or any other place, provided that her going there does not entail anything forbidden.
