فإن أحل رجل من عمرته فقصر من شعره ونسي أظفاره فإنه يجز به ذلك وإن تعمد ذلك أو هو جاهل فليس عليه شئ.
If a person concludes their Umrah and trims their hair but forgets to trim their nails, it is sufficient for them, and there is no penalty. If they intentionally omit it or are ignorant of it, there is still no penalty.
