فضائل أعمال القلوب
‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Belief in evil omens is polytheism. Belief in evil omens is polytheism. Everyone of us experienced something of that, but Allah dispels it with reliance on Him.'' ''Everyone of us experienced something of that, but Allah dispels it with reliance on Him” was said by Ibn Mas‘ūd not the Prophet (may Allah's peace and blessings be upon him).
عن عبد الله بن مسعود -رضي الله عنه- مرفوعاً: "الطِّيَرَةُ شِرْكٌ، الطِّيَرَةُ شِرْكٌ، وما منا إلا، ولكنَّ الله يُذْهِبُهُ بالتوكل". (وما منا إلا، ولكنَّ الله يُذْهِبُهُ بالتوكل) من قول ابن مسعود وليس مرفوعًا.
شرح الحديث :
The Messenger of Allah (may Allah's peace and blessings be upon him) says and repeats, for the sake of emphasis, that belief in evil omens which makes one refrain from doing something or drives him to do it is polytheism, because it entails having one's heart attached to others than Allah and having ill expectations of Him. Ibn Mas‘ūd said that everyone of us experienced something of that pessimism, but Allah removes this feeling with reliance on Him. He might have said that out of modesty and exaggeration coupled with clarification of the treatment in case it happens.
