Fiqh Us-Sunnah: Superagatory Prayers

Sayyid Saabiq (1915-2000 C.E.) wrote the book in Arabic at the request of Imam Hassan al-Banna, the founder of the Muslim Brotherhood (Ikhwan). Every Fiqh ruling on Supererogatory Prayer in the book goes back to the Qur'an and Sunnah and Sabiq dealt with all four madhahib objectively, with no preferential treatment to any.
