وَلَا تَأْكُلُوا مِمَّا لَمْ يُذْكَرِ اسْمُ اللَّهِ عَلَيْهِ
Do not eat from that over which God’s name has not been mentioned. (Qurʾān 6:121, excerpt)
The expression mimmā includes a general relative mā within its relevant domain. The apparent wording covers animals slaughtered without the divine name being mentioned.
The juristic issue is whether deliberate omission and forgetful omission must receive the same ruling. The debate turns on the general verse, the legal treatment of forgetfulness, and the interpretation of related reports.
