Allah knows best.
On the authority of Abu Saeed Al-Khudri (May Allah be pleased with him)
who said: I heard the Messenger of Allah (SallAllahu 'alaihi wa sallam) say, “Whoever of you sees an
evil must then change it with his hand. If he is not able to do so, then
[he must change it ] with his tongue. And if he is not able to do so,
then [he must change it] with his heart. And that is the slightest faith.” (Muslim)
Hating an evil deed, for Allah's sake, shows that you have faith/Imaan,
Hating an evil deed, for Allah's sake, and saying something against that evil deed shows that you have stronger faith/Iman,
Hating an evil deed, for Allah's sake, and (physically) doing something about it (so that evil deed will stop) shows that you have even stronger stronger faith/Iman.
Another example of forbidding what is wrong is when a Muslim sees another Muslim smoking, there are three options that a Muslim can do to carry out his obligations as a Muslim servant of Allah:
1) He can (by hand) take the cigar from the Muslim's hand, throw the cigar away and explain to that Muslim why smoking is forbidden in Islam.
2) He can (by speaking out) tell the Muslim to quit smoking and explain why smoking is bad.
3) If he doesn't have the guts or confidence to speak out, he can hate the evil act of the Muslim smoking and perhaps pray for his brother/sister-in-Islam.
If the Muslim seeing his Muslim bro/sis-in-Islam smoking and actually thinks that it (smoking) is 'cool' or he even wishes that he himself could smoke, then this Muslim could be lacking in faith and should try to improve his Imaan through more good deeds and seeking more Islamic knowledge.
Allah knows best.
