If you have wudu and fall asleep for 10 minutes when making wudu again do you have to do istinja (washing of the private parts) as well?
That which is commonly understood amongst the lay-people that istinja (washing the private parts) must be performed each time one needs to perform wudu, or due to passing wind or sleep in particular, is all incorrect. It is important that a person takes active steps to learn the rules relating to taharah (purification) and other obligatory knowledges that concern him.
In Maraqi al-Falah, al-Imam Shurunbulali (رحمة الله عليه) mentioning that istinja is not performed due to the passing of wind, states: “Because it is pure according to the correct opinion thus (performing) Istinja due to it (the passing of wind) is bid’ah (innovation).”
[Maraqi al-Falah pg 24]
In his Hashiyah on Maraqi al-Falah al-Sayyid al-Tahtawi (رحمة الله عليه) while commenting on the fact that istinja is performed due to najasah exiting the two passage ways, states: “According to this, ritual impurity due to other than this, like sleep and blood-letting exits this rule, thus istinja due to these matters is bid’ah.”
[Hashiyah al-Tahtawi al al-Maraqi pg 44]
Allah knows best.
