Q: I led two people in congregational Prayer after making a valid Wudu' (ablution) and I was certain of my purity. However, while performing Wudu', I saw impurity on my garment. I removed this impurity from the affected part. Although there is no color or any indication that the impurity remains, I could still smell it. I accepted to be the Imam for this Salah only after the two people had insisted. I want to know whether this Salah was valid or not. What is the ruling on those people whom I led in this Salah? Please, guide me. May Allah reward you!
