All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
A good omen is one of the aspects of good expectation of Allaah. The Prophet, sallallaahu ‘alayhi wa sallam, explained what the good omen is when he said: “A good word that anyone of you hears.” [Al-Bukhari and Muslim]
A pleasant scene is like a good word; they are both aspects of the good omen that a Muslim should feel optimistic about, just as the Prophet, sallallaahu ‘alayhi wa sallam, used to do.
Allaah The Almighty Made in this universe many pleasant things and beautiful scenes that awaken the feelings and make the person long for the everlasting pleasure and beauty in the eternal abode in which they will find what no eye has ever seen, what no ear has ever heard and what no mind has ever conceived.
On the other hand, Allaah The Almighty Created and Made in this life ugly things that remind the person of Hell. Accordingly, upon seeing these scenes the person will seek refuge with Allaah from every bad, ugly and harmful thing.
There are many examples in the Quran in this regard. It is an open page that displays the beauties of this universe so that the believer will yearn for the Hereafter and its pleasures.
Likewise, the Quran displays the ugly matters and warns us of them. The Prophet, sallallaahu ‘alayhi wa sallam, used to ask Allaah to shower him with His Mercy when he recited a verse about Mercy; and used to seek refuge with Allaah when he recited a verse about punishment.
Hence, a Muslim in this worldly life should find a good omen and glad tidings and supplicate Allaah when he sees good scenes or hears good words. On the other hand, he should seek refuge in Allaah The Almighty when he hears or sees bad things.
Allaah Knows best.
