Narrated Uqba bin Amir : That the prophet gave him some sheep to distribute among his companions to slaughter as sacrifices . A kid was left and he told the prophet of that whereupon he said to him , ” slaughter it as a sacrifice .”
Narrated Junub : The messenger of Allah (S) said , A man said : By Allah , Allah will not forgive So-and-so , At this Allah the almighty said : who is he who swears by Me that I will not forgive So–and-so ? verily I have forgiven So-and-so and have nullified your deeds (1) or as he said , 1. A similar Hadith , which is given by Abu Dawud , indicates that the person reffered to was a goldly man whose previous good deeds were brought to nought through presuming to declare that Allah would not forgive someones bad deeds .
Narrated Anas (R) : The prophet slaughtered two rams , black and white in color , and I saw him putting his foot on their sides and mentioning Allah’s name and takbir (Allahu Akbar) . Then he slaughtered them with his own hands
