Rulings on the Night Prayers in Ramadhaan.
بـسـم الله والحـمـد لله والـصلاة والـسـلام عــلى رسـول الله، وبـعـد
Brief translation of Shaikh al-`Uthaymeen's " مجالس شهر الرمضان "
O my brothers! Verily, Allaah has legislated for His worship different acts of worship. He made some of these acts as obligatory, and it is not allowed for anyone to reduce from it any act or to breach it. Other acts are supererogatory, with which a person can get even more close to Allaah and which can act as a completion for the deficiencies in the obligatory acts.
