Does taking a birth control pill without water on the morning of the first day of Ramadan break one's fast?

Scholars differ on whether someone who unknowingly consumed something that breaks the fast is required to make up for it (qada') or not. The opinion that qada' is not obligatory is strong and well-supported by evidence, as indicated by Sheikh al-Islam Ibn Taymiyyah and Sheikh Ibn 'Uthaymeen. They cite the Almighty's saying: "And We would not punish until We had sent a messenger," and the hadith of Adi ibn Hatim. Despite the strength of this opinion, making up for the fast (qada') is more cautious and absolves one's responsibility, especially given any negligence in inquiring about and seeking out the rulings of Islamic law.
