What is the ruling regarding a woman observing the 'iddah (waiting period) after her husband's death meeting with men in the presence of others, if she is over the age of fifty?

There is no objection to a woman observing 'iddah (waiting period) after her husband's death meeting men when there is a need, provided that she is properly covered (sā'tirat al-'awrah) and refrains from adornment (tārikat az-zīnah), and that the conversation adheres to the etiquette of Islam.
