Hadith 3916
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " لاَ عَدْوَى وَلاَ طِيَرَةَ وَيُعْجِبُنِي الْفَأْلُ الصَّالِحُ وَالْفَأْلُ الصَّالِحُ الْكَلِمَةُ الْحَسَنَةُ " .
Narrated Anas:The Prophet (ﷺ) as saying: There is no infection* and no evil omen, and I like a good omen. Good omen means a good word. * The majority of scholars interpret this to mean that these things in and of themselves do not transmit or cause harm through supernatural or hidden means but that Allah is ultimately in control and any fearful superstition around these is false
