حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامُ بْنُ يَحْيَى، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ عَدْوَى وَلاَ طِيَرَةَ وَيُعْجِبُنِي الْفَأْلُ الْكَلِمَةُ الْحَسَنَةُ الْكَلِمَةُ الطَّيِّبَةُ " .

Anas reported Allah's Messenger (ﷺ) as saying:There is no transitive disease, no divination, but good omen pleases me, i. e. the good word or a good word. Note: 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
