Islam provides us the best and most effective solutions while trying to convince others about the truth.
Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided. [Qur'an: 16:125]
This principle of instructing others with wisdom is amply demonstrated in the hadith that follows. See how the Messenger of Allah (SAWS) answered in the best and most effective way that made the young lad see sense.
A young man of the Quraish came to the Prophet one day and said: "O Prophet! Give me permission to commit adultery." Some of the Companions who were present, seeing this request as being against Islamic morals, told him to be quiet and scolded the young man. Prophet Muhammad was very calm and told the young man "Come over here and sit down." Then he turned to him and started to talk with him. "Tell me, would you like for another to commit adultery with your mother?" The young man said "O Prophet of Allah, I would never desire such a thing." The Prophet said: "No one would want such a thing for their mother." He continued, and said: "Would you want someone to commit adultery with your daughter?" The young man said "O Prophet of Allah, I would not." The Prophet said: "No one would want for their daughter to commit adultery." Then he went on to ask if the young man would approve of his sister, paternal aunt or maternal aunt committing adultery. Each time, the young man answered: "No, I would not want that." When he saw that the youth had understood his error the Prophet put his hand on the young man's shoulder and said "My Lord, forgive him his sin, clean his heart and protect him from committing sins." The young man, according to his own words, did not allow the emotion of lust to enter his heart again. [Ahmad b. Hanbal, Musnad, Beirut, IV, 256-257]
Attraction towards women is natural for any man, and a Muslim too is no exception. However, before trying to justify fahisha (indecency) to yourself and to others, bear this hadith in mind and ask yourself: Would you like it if your mother and sister and aunts all dressed up that way and every inch of their bodies was then admired by men? Would you like the ladies of your household to be ogled at?
Answer that to yourself, and you will get your answer. Islam is natural and only promotes that which is natural. No man would like that the women of his household were ogled at, and Islam formalizes this formal fitrah or nature of man. Do unto others as you would have others do unto you.
