[death]
Something I noticed is that in general non-Muslims or more specifically irreligious people, when met with bad news, after the natural shock and disbelief, generally start asking why something happened, despairing, and wondering what they did to deserve this, etc.

The response of Muslims, especially in Muslim majority societies, is very different!
The person receiving the news may be in shock or disbelief about the news, some even faint, while others immediately mention God.

Even if the person receiving the news doesn’t immediately say “To God we belong and to Him is our return” (which Muslims ought to say when struck by any sort of calamity or affliction, but, people commonly only say it for death.)

For most, there’s none of that “why me,” no doubting in God, no sense of betrayal, nor behaving as if it’s a punishment...
It was ordained for them to return to God at that time. The same One who gave this person life, who allowed them to meet, has taken them back.

“The pens have been lifted and the pages have dried.” -Muhammad, peace be upon him.

“No misfortune can happen on earth or in your souls but is recorded in a decree before We bring it into existence: That is truly easy for Allah:”
[57:22, Quran]

I’ve seen these scenes many, many times in hospital. Some older women faint, but no one goes “why?!” or shows discontent with destiny, and the people around them always urge them gently, but insistently to mention God to bear it more easily... if they even need to remind them.

It comes naturally when Muslims as a whole mention God at all times and in all affairs, good or bad, in matters big or small.
