Slaughtering in gratitude to Allah after obtaining what was sought

Question:
And the Shaykh’s (may Allah grant you success) other question: What is the ruling on slaughtering in general after obtaining what was sought, as a thanksgiving to Allah?

Answer:
There is no harm in slaughtering for Allah (Mighty and Majestic) and giving its value in charity; this is an act of worship. If you slaughter it and give the meat in charity to those in need, this is an act of worship, because charity is an act of worship. However, if you slaughter for the rich or for people who are not in need when something happens that makes you happy, this is from the permissible things; it is from the permissible things, not from acts of worship. For example, you passed the exam and closed the deals; this is permissible, and for them it is an act of worship—this is a permissible thing. Or a new house was built for the plants in the Jafara and Ma'arif camps, and they are rich, and they are in need; this is from the permissible things.
