Please note in the above post how many times Halal appears with Tayyab.
I am grateful to my intelligent friends who teach me or encourage me to learn something new every day. May Allah bless you all!
QXPv glossary: Tayyab = Decent and clean = Of one's liking = Not forbidden in the Qur’an = Good for mind and body = Pleasant.
I have looked at Mufridat Raghib fi Gharib-il-Qur'an (Arabic, 1373 A.H. Maktaba Adnan, Beirut) today for TAYYAB and found additional, detailed meanings.
- Must be Halal.
- Very frequently Halal & Tayyab come to be synonymous.
- It should look pleasing to the eye.
- Of one's liking: only so that one does not feel forced to eat all Halal things.
- When cooked, it generates saliva with its sight, smell, steam and taste.
- And thus it is enjoyable to eat.
- Easy to chew and swallow.
- It pleases the host and the guests.
- It must be pleasing to human 'psyche' and aesthetics.
- All birds except scavengers are Tayyab.
- Should be wholesome, clean and healthy.
- A Tayyab food is always a delight to share with your family and friends.
- Ugly animals can never be Tayyab even after slaughter and cut.
- Allah's frequent inclusion of Tayyab with Halal is an extremely important point for mu'mins to remember.
[Translated from eloquent Arabic, might need editing. Notice how careful the great Imam has been not naming animals except birds as a group. He has not called scavenger birds and animals HARAM, although he states early on that only HALAL food can be TAYYAB.]
