Question: My question is, if it drips in tiny amounts in our underwear specifically, is our underwear included in the clothing that must be washed before we enter Salat, or is it only outer garments that need to be clean?
Answer: Wa alaikum assalam wa rahmatullahi wa barakatuh,
I hope you are in the best of health and spirits, insha’Allah.
Yes, one’s under garments are included in that which must be clean before initiating one’s prayer.
However, up to 5cm in diameter of liquid filth on one’s body or clothing would be excused. [Shurunbulali, Maraqi al-Falah; `Ala al-Din `Abidin, al-Hadiyya al-`Ala’iyya]
