The ruling on one who completed 'Umrah but did not shave or shorten his hair!!
Machine translationRead the Arabic original
The questioner : This man says: I performed tawaf and sa'y for 'Umrah, but I forgot to shave. What should I do now?
The Shaykh : The man is present now. Is the questioner there? In any case, he is hearing me now. He must now remove his regular clothes. If he is wearing a ghutrah or a taqiyah now, he must remove them. Then he should go straight to his house and put on the clothes of ihram, because he has not yet exited the state of ihram. Then he should shave or shorten his hair, and return to put on his usual clothes.
