Question: I have a habit of playing with my hair when I am thinking. After I had entered the state of ihraam, I forgetfully did this and some hair fell out. Do I have to make an expiation?
Response: There is nothing required of you due to that which Allaah سبحانه و تعالى mentions regarding the believers that they said:
{Our Lord! Punish us not if we forget or fall into error...} al-Baqarah 2:286
And Allaah has responded to their request as it has been mentioned on the authority of the Messenger of Allaah ﷺ that Allaah سبحانه و تعالى said:
«I have done [this]» [transmitted by Muslim no.126]
