Question Detail:

Calcium hydroxide (slaked lime) and betel-nut are eaten with betel leaves. Somebody took his obligatory bath and prayed both fajr and ishraq salaats. After ishraq he noticed a small spot of lime on one of his fingers which appeared as a remnant of his last night’s betel leaf eating. What should he do for his salaats already prayed?

Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh

If the spot of lime was a mere coloring on the skin and not a layer on the skin, then the salah will be valid.
 
And Allah knows best
