أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا عَدْوَى وَلَا طِيَرَةَ وَالشُّؤْمُ فِي ثَلَاثٍ فِي الْمَرْأَةِ وَالدَّارِ وَالدَّابَّةِ
Allah's Messenger (ﷺ) said, "There is neither 'Adha (no contagious disease is conveyed to others without Allah's permission) nor Tiyara, but an evil omen may be in three a woman, a house or an animal."
Bukhari 5312
سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَا طِيَرَةَ وَخَيْرُهَا الْفَأْلُ قَالُوا وَمَا الْفَأْلُ قَالَ الْكَلِمَةُ الصَّالِحَةُ يَسْمَعُهَا أَحَدُكُمْ
I heard Allah's Messenger (ﷺ) saying, "There is no Tiyara, and the best omen is the Fal." They asked, "What is the Fal?" He said, "A good word that one of you hears (and takes as a good omen)."
