Shaykh Ibn Uthaymeen was asked:

Question:

“What is the ruling on hosting guests if a man builds a new house?”

Answer:

“There is nothing in it and it is not prohibited nor an innovation. This is what is from the customs of the people. They host guests out of joy of a building a new house and honoring their brothers. There is nothing in this. [Liqa al-Baab ul-Maftooh no. 172 found here]
