(Part 1) In the Quran verse 7:77, Allah swt blames the people collectively for killing the camel and disobeying His command, when it was one man who killed the camel. So this verse is saying the People agreed with his actions and so were accountable despite not physically doing anything. My question is how can this manifest in modern ways? For example if we were to like or reblog a picture that wasn't Islamic would that count as agreeing with it [CONT. ]
(Part 2) (E. G: if I liked a picture of a model on Instagram would I be accountable for her Sin? ) It might not seem related but I'm trying to reflect the verse to myself and am thinking of ways we might enact it today. But I also have a tendency to overthink things so require more opinions.
The people of Thamud had already rejected their prophet’s message for years before that happened. This “collective” judgment was not for a single sin. God had already decided that they deserved destruction prior to sending them the camel. The camel was the final “sign” for them. They were promised that if they killed it, the final destruction would come upon them. Since the people all rejected the prophet’s message, they had no trouble with killing the camel. So when they did that the destruction came to them.
The example you gave is not really related unless you thoroughly take part in something that is reprehensible to God and involves a rejection of the Prophet’s message , for example constantly reblogging posts that make fun of the Quran.
Liking or reblogging a model’s picture is a different and much less serious issue, although it might still be sinful depending on the particular photo and its context.
