Making dua for something that seems improbable
Q: Is it disliked to make dua for something that is highly improbable?
Secondly, does making dua such as 'oh Allah, grant jannah to all of the ummah' count as improbable since some people will inevitably go to jahannam? Or asking Allah to protect all of the our brothers and sisters from Allah all sorts of harm - is this also improbable?
