Anas b. Malik reported Allah's Messenger as saying: There is no transitive disease, no divination, but good omen pleases me. It was said: What is good omen? He said: Sacred words.
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 " .
