Does taking off Ihram without Umrah necessitate Dam?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
Taking off ihram and wearing stitched clothing for an entire day will necessitate an animal sacrifice, Dam. If it was less than a day, then half a ṣā’ of wheat or barely [about approx. 1.5 liters or 1.5 kilograms] should be given in charity or the equal amount in money [about $2.50 as of Feb 2020].
Only Allah knows best
