Your Sins Are forgiven even if they Are foam of sea. If you say Subhaan Allaah wa bi hamdih (Praise and glory be to Allaah) one hundred times.

It was narrated that Abu Hurayrah said: The Messenger of Allaah ﷺsaid:

“Whoever says Subhaan Allaah wa bi hamdih (Praise and glory be to Allaah) one hundred times, morning and evening, his sins will be erased even if they are like the Foam of the sea.”
