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.
