Les Proverbes 21:27 Halakha : Mishneh Torah, Foreign Worship and Customs & Kitzur Shulchan Arukh

Fruit on the trees therein is permitted; for, it is said: "shalt gather" and "shalt burn" (Deut. 13.17.), such should be destroyed as require only gathering and burning, whereas fruit on the trees require gleaning, gathering and burning. This is also applicable to hair on one's head. Needless to say that the trees themselves are permitted, and are, of course, the property of the heirs. The devoted things therein are dealt with as follows: the devoted animals of the altar should be destroyed; "The sacrifice of the wicked is an abomination" (Prov. 21. 27.); the devoted things for the repair of the Temple should be redeemed, and thereafter burned, for it says, "Spoil of it" (Deut. 13.17.) but not spoil of heaven.¹⁸Sanhedrin, 112b. C.

If you prayed and later found that the place contained excrement—¹⁰Within four amohs if it was a place that should have been inspected for possible excrement and you neglected to inspect it, since the prayer of the Shemoneh Esrei is in place of a Sacrificial offering, this Scriptural verse is applicable, "The sacrifice of the wicked is abominable"¹¹Proverbs 21:27. and you are therefore required to repeat the Shemoneh Esrei. Similarly, in regard to Shema which is a Biblical command; since there is no problem of reciting a berachah in vain you must again recite the Shema, without the berachos.¹²According to Mishnah Berurah, you should repeat the berachos. Likewise other berachos recited there, and even the Birkas Hamazon, need not be repeated.¹³According to Mishnah Berurah you should repeat the Birkas Hamazon. If the place is one that did not require inspection for excrement, you are not considered negligent, and even in regard to Shemoneh Esrei your obligation is fulfilled. If urine is found, even in a place where its existence should have been suspect, your obligation is fulfilled even in regard to Shemoneh Esrei.
