أحسن الله إليكم, my teacher. I worked with plaster and had dried primer on my hands and nails that I only noticed after salah. I removed it and prayed salah again, but later found tiny remaining spots visible only in light and a perhaps 2 a bit bigger on my nail. Are my wudu and salah valid?

Ustadh AbdulAziz al-Haqqan

Yes valid don't exaggerate
