Jumu'ah or Friday prayer is an important part of Islamic practice that is mentioned in the Quran. It serves as a weekly spiritual renewal for Muslims where they can reflect on religious teachings and guidance. There are also sunnah practices associated with Friday, such as taking a bath, wearing clean clothes, going early to the mosque, and reciting Surah Al-Kahf. Reciting this particular chapter is highly recommended on Fridays due to benefits like protection from evil, receiving blessings, increasing knowledge and wisdom, and learning from its inspirational stories.
