Through the infinite grace and assistance from Allāh Taʿālā alone, He  has granted us the tawfīq to begin this task of sharing important information and masā’il regarding menses (Ḥayḍ), dysfunctional uterine bleeding (Istiḥāḍah) and lochia (Nifās) mainly sourced from “Manhal al Wāridīn”, ʿAllāmah Ibn ʿĀbidīn al-Shāmī’s رحمه الله commentary on Imām Birgivī’s رحمه الله “Dhukhrul Muta’h-hilīn”.

“The validity of many other rulings is based on this such as: ṣalāh, fasting, reading and touching the Qur’ān, iʿtikāf, entering the Masjid, ṭawāf of Ḥajj, puberty, divorce, ʿiddah, permissibility of intercourse, lineage.” [ʿAllāmah Shuranbalālī رحمه الله]
