:-> Is it permissible to offer a sacrifice in gratitude to Allaah for a specific blessing?

:->
The view of the Hanbalis, the more correct view among the Shaafa’is, is that these meals are mustahabb.
Ibn Qudaamah said: Theseinvitations – other than the wedding feast (waleemah) and ‘aqeeqah– are something good, but they are like invitations that are given for no reason; if the person who does them intends thereby to give thanks to Allaah for His blessing and to feed his brothers and offer food, then he will have the reward for that in sha Allaah. End quote.
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) was asked:
If one of my children doeswell in school, is it permissible for me to offer a sacrifice to celebrate his success, and to give thanks to Allaah?
He replied:
There is nothing wrong with making food (waleemah) if the childrenor one of them succeeds, and inviting one’s loved ones and his child’s friends, to celebrate Allaah’s blessing and to encourage the child. End quote.

Secondly:
It is essential to beware ofsome beliefs which many people hold, and say that in order to protect the new house or car it is essential to offer a sacrifice and sprinkle it with the blood of the slaughtered animal, or that evil spirits will not keep away from you unless you do that, otherwise the blessing will soon dissipate. hese are jaahili beliefs which do not come from someone who believes in Allaah as his Lord Who possesses all powers to bring benefit or cause harm, in Whose hand is the creation and the commandment, and knows that it is not permissible to do acts of worship unless they are done for the sake of Allaah.
The scholars of the Standing Committee wereasked about the belief held by many people, thatoffering a sacrifice on the threshold of the new house before entering it isone of the most important means of warding off the evil eye, and making the house blessed, and avoiding calamities and undesirable events.
They replied:
If this custom – i.e., offering a sacrifice on the threshold of the new house – is done in order to placate the jinn and ward off calamities and undesirable events, then it is a haraam custom, andis in fact shirk. This is what seems to be the case with offering the sacrifice before entering the house, and doing it onthe threshold in particular.
But if the intention is to honour one's new neighbours and get to know them, and to give thanks to Allaah for the blessing of a new home, and to honour one's relatives and friends on this occasion, and to showthem the house, then this is good and the one who does it is to be praised forhis action. But that is only usually done after the people have moved into the house, and not before,and the animal or animalsshould not be slaughteredon the threshold of the house or in the entryway to the house.

And Allaah knows best.
