Is it permissible to shorten the khimar and fasten it with a pin when wearing a coat for work? Is the questioner sinful if her hand occasionally appears without a glove? And is greeting employees with "Al-Salam Alaykum" considered a fitna?

The Shari'ah has not specified a particular dress for women. Rather, it has stipulated certain conditions that must be met for a garment to be considered a legitimate hijab. A woman must cover her entire body in front of non-mahram men, with a difference of opinion regarding the permissibility of uncovering the face and hands when there is no fear of temptation (fitnah). As for greeting men with salaam, it is permissible when there is no fear of temptation.
