‘This is a thing (i.e. an imagination) which any of you finds it in your heart. However, may it not prevent you (from your need, etc.) (Muslim, pp. 1223, Hadees. 537)  

It is narrated that a person came to the blessed court of the Holy Rasool
صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم and humbly said: ‘Ya Rasoolallah صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, we used to live in a house. We had abundant of household and wealth in it. Then, we changed our house which resulted in a reduction in our household and wealth.’ Holy Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم said: ‘Leave it! It is bad to say such thing.’ (Adab-ud-Dunya wad Deen, pp. 276)

Dear Islamic brothers! After listening to the aforementioned blessed Ahadees condemning bad omen, we came to know that a person falling prey to bad omen remains deprived of attaining high ranks. Regarding such person, Holy Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated that he is not upon our way. Similarly, while complaining about his house, when a blessed companion رَضِىَ اللهُ تَعَالٰی عَـنْهُ said that since we shifted in this house, there has been reduction in our household and wealth. Then Holy Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم straightaway denied this thought and said: ‘It is bad to say so.’ Unfortunately, the bad omen is so common in our society that we are seen falling prey to it upon every smallest of the matters. For example:

Fatwa of A’la Hadrat regarding bad omen

At times, upon listening to the ambulance or fire brigade while going for a new employment, people develop a mindset that they will not succeed today. At times, if the first customer leaves without buying anything, then shopkeepers consider it to be a bad omen. Similarly, people don’t let a pregnant woman go near a deceased and at times, a woman becoming widow at a young age is called bad-omened and her feelings are hurt by calling her to be inauspicious, she becomes a victim of slandering and evil-presumption and various other bad names are given to her.

Remember! Islam has declared it ‘Haraam to consider someone to be accursed (منحوس) in this way. A similar kind of question was asked to my master, A’la Hadrat, Imam of Ahl us Sunnah, revivalist of Sunnah, Maulana Imam Ahmad Raza Khan رَحْمَةُ اللهِ تَعَالٰی عَلَيْه that:
