Berakhot 8:48

['These are the matters of dispute between Beit Shammai and Beit Hillel with regard to the halakhot of a meal: One dispute concerns the order of blessings in kiddush. Beit Shammai say: When one recites kiddush over wine, one recites a blessing over the sanctification of the day and recites a blessing over the wine thereafter. And Beit Hillel say: One recites a blessing over the wine and recites a blessing over the day thereafter.', 'Similarly, Beit Hillel and Beit Shammai disagree with regard to drinking wine before a meal. Beit Shammai say: One washes his hands and mixes water with the wine in the cup thereafter, and Beit Hillel say: One mixes water with the wine in the cup and only washes his hands thereafter. The basis of this particular dispute is with regard to the laws of ritual purity, as the Gemara will explain below.', 'Also with regard to the laws of ritual purity, Beit Shammai say: After washing, one dries his hands with a cloth and places it on the table. And Beit Hillel say: One places it on the cushion upon which he is sitting.', 'Similarly, Beit Shammai say: One sweeps the area of the house where the meal took place and he washes his hands with the final waters before Grace after Meals thereafter. And Beit Hillel say: One washes his hands and sweeps the house thereafter.', 'Just as they dispute the order of the blessings in kiddush, they dispute the order of the blessings in havdala. If a meal continued until the conclusion of Shabbat, Beit Shammai say: One recites the blessing over the candle, then the Grace after Meals blessing, then the blessing over the spices, and finally the blessing of havdala. And Beit Hillel say: The order is candle, spices, Grace after Meals, and havdala. With regard to the blessing over the candle, Beit Shammai say: Who created [bara] the light of fire. And Beit Hillel say: Who creates [boreh] the lights of fire.', 'One may neither recite a blessing over the candle nor over the spices of gentiles, nor over the candle nor the spices designated to pay respects to the dead, nor over the candle nor the spices of idolatry. The mishna cites another halakha with regard to the blessing over the candle: And one does not recite the blessing over the candle until he derives benefit from its light.', 'The mishna cites an additional dispute: One who ate and forgot and did not recite a blessing; Beit Shammai say: He returns to the place where he ate and recites the blessing. Beit Hillel say: That is unnecessary. He recites the blessing at the place where he remembered. Both agree, however, that there is a limit with regard to how long after eating one may recite Grace after Meals. And until when does he recite the blessing? Until the food is digested in his intestines.', 'Wine came before the diners after the meal; if only that cup of wine is there, Beit Shammai say: One recites a blessing over the wine and recites a blessing over the food, Grace after Meals, thereafter. And Beit Hillel say: One recites a blessing over the food and recites a blessing over the wine thereafter. And one answers amen after a Jew who recites a blessing even if he did not hear the entire blessing, and one does not answer amen after a Samaritan [Kuti] who recites a blessing until he hears the whole blessing in its entirety, as perhaps the Kuti introduced an element inconsistent with the Jewish faith in that section of the blessing that he did not hear.']
