What are the websites that offer audio lessons for the interpretation of the Holy Qur’an, and what are the ways a Muslim woman can serve Islam while in a foreign country?

Audio lessons on Tafsir are available from a number of shaykhs online, such as Sheikh Al-Uthaymeen, Ibn Baz, Al-Jazairi, and Al-Sha'rawi. Websites like Islamway and Sultan are full of useful resources.

To serve Islam, a Muslim must worship Allah and strive to make others worship Him. This is done by upholding Allah's command in one's home and family, in accordance with the verse: "O you who have believed, protect yourselves and your families from a Fire," and in one's clan and neighborhood, in accordance with the two verses: "And warn, [O Muhammad], your closest kindred," and "That you may warn the Mother of Cities [Makkah] and those around it." One should also be concerned with guiding the entire Ummah, starting with honoring parents, raising children, maintaining ties of kinship, and being good to neighbors.
