Riyad as-Salihin 1674
Anas (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "Not the transmission of disease of one person to another and no evil omen, but I am pleased with good omens." He was asked: "What is good omen?" He replied, "A good word." [Al-Bukhari and Muslim] .
عن أنس رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم ‏:‏ ‏"‏لا عدوى ولا طِيَرة ويعجبني الفأل‏"‏ قالوا‏:‏ وما الفأل‏؟‏ قال‏:‏ ‏"‏كلمة طيبة‏"‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
