It sounds to me that they're trying to work around their own beliefs which is just weird to say the least.
Yea if we look at the title alone we could say that they are misleading the public base on there belief but going through the entire video the speaker is actually making some points and it’s not encouraging gambling but rather he is advising those Muslim who already found them self in the means of gambling to not use that as an excuse of not praying because of the surrounding that they finds their self that doing that could be seen as a double sin, anyone who see any Muslim in the means of gambling should not also stop them from praying that they should allow them pray, that everything is done one step at at time, with them doing a little of good thing and praying always that they will have better chances of realizing that they are committing a great sin and are likely to change and come out of the sin over time, But discouraging them and calling them siners won’t help the matter at all, he also gave an instance of those who see people who dress half native that it’s better to advise them to dress decently than telling them to completely remove the cloth since they choose to be naked. I finds his teachings educative rather than weird.
Yes, it is quite misleading and worse could spread misinformation if not read the article fully or even watched the video. Of course, clashing with your cultural or religious beliefs will be difficult. It not only gave you an obligation to change and do the right thing but also to give up what you are doing the wrong thing.
Will you give up your beief instead to gamble? or you'll give up gambling and change and stick with your truth and belief? There is no right and wrong answer because we have different values from different backgrounds. But what I know is living against your moral values is not easy.
