Question
Is there a dua to stop bleeding from a cut/spot pimple etc.
Answer
When the Sahaba would be injured on the battlefield the Prophet sallallahu alayhi wasallam would pay special attention to their medical needs; he would nurse them and provide medical assistance for them. This is the Sunnah way and we should be holding on to that, so go to the doctor, have some bandages applied to the cuts and then ask Allah to give you a complete and speedy recovery.
