The Prophet ﷺ 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. (Using translation from Abū Dāʾūd 3920)   

أَنَّ النَّبِيَّ ﷺ كَانَ لَا يَتَطَيَّرُ مِنْ شَيْءٍ وَكَانَ إِذَا بَعَثَ عَامِلًا سَأَلَ عَنِ اسْمِهِ فَإِذَا أَعْجَبَهُ اسْمُهُ فَرِحَ بِهِ وَرُئِيَ بِشْرُ ذَلِكَ فِي وَجْهِهِ وَإِنْ كَرِهَ اسْمَهُ رُئِيَ كَرَاهِيَةُ ذَلِكَ فِي وَجْهِهِ وَإِذَا دَخَلَ قَرْيَةً سَأَلَ عَنِ اسْمِهَا فَإِنْ أَعْجَبَهُ اسْمُهَا فَرِحَ بِهَا وَرُئِيَ بِشْرُ ذَلِكَ فِي وَجْهِهِ وَإِنْ كَرِهَ اسْمَهَا رُئِيَ كَرَاهِيَةُ ذَلِكَ فِي وَجْهِهِ
