Doubting if one had wudhu when one lead the Salaah
Q: A person was in 30% doubt about whether he had wudhu, but gave himself the benefit of the doubt and attended the masjid. He was called to lead the salah as the imam was not present. After salaah this doubt becomes 70% sure that his wudhu had broken previously.
1) What is the condition of his salaah, and all the Muqtadis?
2) if he was 100% sure now that his wudhu had broken, what now would be the ruling?
