A woman’s husband has passed away, and she is now in her waiting period of mourning. It is known that adornment in body and clothing is forbidden for her during this time. She asks: 1.Is it permissible for her to attend her sister’s wedding, knowing that she will not wear decorative clothing or perfume, but that in the wedding there will inevitably be pleasant scents such as incense and perfumes, along with clapping and expressions of joy? 2.Is it permissible for her to attend the celebrations of the Ahl al-Bayt (PBUT), where it is customary for attendees to have rosewater sprinkled on their faces, which has a pleasant fragrance, and to participate in recitations and chants that involve joy and happiness?
