Without performing Istinjaa (cleansing oneself after using the bathroom), I performed Wudu' (ablution) to perform Maghrib (Sunset) Prayer.
I was certain that I had not experienced a minor ritual impurity that necessitates Istinjaa. I led another person in Maghrib Prayer. When it was time to perform `Isha' (Night) Prayer, I performed it individually without renewing my Wudu'. When the time of Fajr (Dawn) Prayer was due, I went to perform Wudu' but I found that I had experienced a minor ritual impurity since the time of Maghrib Prayer. Therefore, I performed the Maghrib and `Isha' Prayers again with the Fajr Prayer.As for the person I led in Maghrib Prayer, he knew nothing of what I have mentioned here until now.Now, was I wrong when I performed Maghrib and `Isha' Prayers again? If so, what shall I do? Is the Salah performed by the person I led valid? (Part No. 6; Page No. 193) If not, what shall I do? May Allah grant us all success in doing what He likes and what pleases Him.
Firstly, performing Istinjaa is necessary only when a discharge other than wind is emitted from the anterior and posterior private parts. Performing Istinjaa is to remove the impurity from these parts either with water, stones, or the like. Secondly, it is not necessary to perform Wudu' immediately after Istinjaaa. For instance, if someone has experienced a minor ritual impurity in the morning and made Istinjaa without performing Wudu', it is sufficient for him to perform Wudu' only without Istinjaa when the time of Zuhr Prayer is due. Accordingly, the Salah performed in this case is valid. Thirdly, the Salah led by an Imam who has experienced a minor ritual impurity and forgets is valid. People led by such an Imam should not perform the Salah again, if they do not know this fact, while the Imam should do so.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
