How can a single Muslim woman living alone ascertain the presence of jinn in her home, and what are the detailed procedures for expelling them, given that she adheres to the morning and evening remembrances?

There is no way to know if jinn are present in the house. However, to expel them, you should recite Surat Al-Baqarah, Ayat Al-Kursi, and its last two verses. Also, maintain the morning and evening remembrances, the remembrances before sleep, perform prayers on time, and observe night prayers. It is advisable to have one of your sisters or another woman stay with you overnight, and to seek a righteous husband.
