The Apostle of Allah then said: When one of you eats food, he should say: O Allah, bless us in it, and give us food (or nourishment) better than it.

Hadith - Abu Dawud, Narrated Abdullah ibn Abbas

Hadith - Abu Dawud, Narrated Abdullah ibn Umar

The Apostle of Allah prohibited eating the animal which feeds on filth and drinking its milk.

Hadith - Al-Tirmidhi, Narrated Salman

When Allah's Messenger was questioned about clarified butter, cheese and wild asses, he replied, "What is lawful is what Allah has declared lawful in His Book; what is unlawful is what Allah has declared unlawful in His Book; and what He has said nothing about belongs to the things He ignores."

[Ibn Majah and Tirmidhi transmitted it, Tirmidhi saying this is a gharib tradition which, according to the soundest opinion, is mawquf].

The Noble Qur'an Al-Imran 3:115-116

He has forbidden you only Al-Maytatah (meat of a dead animal), blood, the flesh of swine, and any animal which is slaughtered as a sacrifice for others than Allâh (or has been slaughtered for idols etc. or on which Allâh's Name has not been mentioned while slaughtering). But if one is forced by necessity, without wilful disobedience, and not transgressing, then, Allâh is Oft-Forgiving, Most Merciful.

And say not concerning that which your tongues put forth falsely: "This is lawful and this is forbidden," so as to invent lies against Allâh. Verily, those who invent lies against Allâh will never prosper.

Forbidden Meats

The Noble Qur'an - Al-Ma'idah 5:3

Forbidden to you (for food) are: Al-Maytatah (the dead animals - cattle-beast not slaughtered), blood, the flesh of swine, and the meat of that which has been slaughtered as a sacrifice for others than Allâh, or has been slaughtered for idols, etc., or on which Allâh's Name has not been mentioned while slaughtering, and that which has been killed by strangling, or by a violent blow, or by a headlong fall, or by the goring of horns - and that which has been (partly) eaten by a wild animal - unless you are able to slaughter it (before its death) ­ and that which is sacrificed (slaughtered) on An­Nusub (stone altars). (Forbidden) also is to use arrows seeking luck or decision, (all) that is Fisqun (disobedience of Allâh and sin). This day, those who disbelieved have given up all hope of your religion, so fear them not, but fear Me. This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islâm as your religion. But as for him who is forced by severe hunger, with no inclination to sin (such can eat these above-mentioned meats), then surely, Allâh is Oft­Forgiving, Most Merciful.

The corpse of locusts, fish, the livers, spleen of blood are lawful. So the Prophet (SAW) said: He has made two dead things and blood lawful: the locusts and the fish, the liver and the spleen.

Baihaqi and others have recorded it as 'marfu' type of hadeeth as also 'mauquf' type. The 'isnad' od 'mauquf' is authentic and it is as good as 'marfu' tradition, since it is not stated in the form of a 'ra'y' (decision based on one individual's judgement not on Qur'an and Sunnah).

The Noble Qur'an - Al-An'am 6:145

Say (O Muhammad SAW): "I find not in that which has been inspired to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maytatah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork, etc.) for that surely is impure, or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allâh (or has been slaughtered for idols, etc., or on which Allâh's Name has not been mentioned while slaughtering). But whosoever is forced by necessity without wilful disobedience, nor transgressing due limits, (for him) certainly, your Lord is Oft­Forgiving, Most Merciful."

The Sunnah has forbidden many things not mentioned in the verse mentioned above, as for example in the saying of the Holy Prophet (SAW): All predatory animals with tusk and every bird with claw are forbidden for consumption. There are other traditions which have forbidden the consumption of such animals as the Prophet (SAW) is reported to have said on the Day of Khayber: Allah and His Messenger have prohibited the consumption of domesticated asses, for they are filth.
