Abu Dawud Book 23, Hadith Number 3910.

Narated By Buraydah ibn al-Hasib : The Prophet (PBUH) did not take omens from anything, but when he sent out an agent he asked about his name. If it pleased him, he was glad about it, and his cheerfulness on that account was visible in his face. If he disliked his name, his displeasure on that account was visible in his face. When he entered a village, he asked about its name, and if it pleased him, he was glad about it, and his cheerfulness on that account was visible in his face. But if he disliked its name, his displeasure on that account was visible in his face.
