Sahih Muslim 2224
Sahih Muslim · Book 39: The Book of Greetings · (Evil) Omens And Al-Fa'l, And That Which May Be Regarded As Inauspicious
Anas b. Malik reported Allah's Messenger (ﷺ) as saying:
وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى ، وَابْنُ، بَشَّارٍ قَالاَ أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، حَدَّثَنَا شُعْبَةُ ، سَمِعْتُ قَتَادَةَ ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ عَدْوَى وَلاَ طِيَرَةَ وَيُعْجِبُنِي الْفَأْلُ " . قَالَ قِيلَ وَمَا الْفَأْلُ قَالَ " الْكَلِمَةُ الطَّيِّبَةُ " .
There is no transitive disease, no divination, but good omen pleases me. It was said: What is good omen? He said: Sacred words.
