I said: Inform me, if this woman wants to leave the house for a matter of necessity, what should she do? He said: She should leave after midnight and (at the latest) return at the time of Isha.

✅According to the above narrations, it is obligatory for a woman during the waiting period of mourning to observe 'hidad' and not adorn herself, and some examples of adornment are mentioned in the above narrations, such as using perfume, wearing colored clothes, using kohl, wearing jewelry, and so on.

✅Also, in Shia narrations (including 📚Al-Kafi, Vol. 6, p. 426), getting married during the waiting period of mourning is completely forbidden.

✅Regarding speaking with a stranger, there is no difference between the waiting period and other times, and the same general rules apply.

✅In the above narrations, colored clothing is forbidden for a woman during the waiting period of mourning, but the amount of covering in front of a stranger does not differ from other times.

✅In hadith 2 and others, due to the general prohibition of a woman adorning herself during the waiting period of mourning, she should also avoid other forms of adornment that are common today.
