A mourning woman going out for Tarawih and `Umrah

Q: I would like to tell Your Eminence that my father has recently died (may Allah be merciful to him). Since my mother is observing `Iddah (woman's prescribed waiting period after widowhood), she has asked me to greet you and ask you about the following:First: Is it permissible for her to go to the Masjid (mosque) to offer the Tarawih (special supererogatory night Prayer in Ramadan) and Tahajjud (optional late night Prayer) in congregation?Second: She lives in a house next to my house and that of my sister. The three houses can be opened to one another and are surrounded by one fence. Is it permissible for my mother to go out of her house to have lunch or dinner or to spend the night at either of these two houses?Third: If the members of the three houses move to Makkah to perform `Umrah (lesser pilgrimage) during Ramadan, is it permissible for my mother to move with them?Fourth: My father (may Allah be merciful to him) has another house in which his other wife and children live. If they are holding a banquet in their house, is it permissible for my mother (Part No. 20; Page No. 451) to attend it or to go there to visit them?Fifth: Is it permissible for my mother to apply kohl (antimony powder eyeliner) for medical purposes and not for adornment? Is she permitted to henna or comb her hair?Sixth: Do menopausal women have different rulings regarding `Iddah and Hidad (prescribed mourning period during which a widow does not adorn herself and keeps to the home of her deceased husband)? Seventh: Is it permissible for my mother to drink saffron as a sort of medication?I have already read your valuable assay about `Iddah and told my mother some of its rulings, but she insists on knowing the opinion of Your Eminence. Since Allah (Blessed and Exalted be He) has ordered Muslims to obey their parents, I have done as she tells me and I hope you would honor me with a detailed answer and illustration of what may be difficult for her to understand. I ask Allah (Exalted be He) to forgive my father and admit him into Jannah (Paradise) and to grant my mother a long life, bless her Rizq (sustenance), and make her offspring righteous. May Allah reward you the best for us and for all Muslims and guide you to what benefits the Ummah (nation based on one creed).
