Al-Adab Al-Mufrad, Hadith 913 ⓘ
Anas reported that the Prophet, may Allah bless him and grant him peace, said, "There is no infection and there are no bad omens, although I am pleased by a good omen - a good word."
حَدَّثَنَا مُسْلِمٌ، قَالَ: حَدَّثَنَا هِشَامٌ، قَالَ: حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم: لاَ عَدْوَى، وَلاَ طِيَرَةَ، وَيُعْجِبُنِي الْفَأْلُ الصَّالِحُ، الْكَلِمَةُ الْحَسَنَةُ.
