My few points....
Source of Evil: Shaitaan .. he will whisper.. and he will make us see bad.. disturbs our heart.. runs through the blood of people in bad environment/ bad intention and bad action... And shaitaan is not gonna stop that unless the Qayamat comes.
So bad people will be there...(irrespective of any religion) It is our duty to protect ourself from shaitaan.
Make your home a Masjid... free from photographs, music, .. make it clean and pure.. Shaitaan will run away.
Keep your heart clean.. make ur ears listen to quran.. avoid music.. think about ALLAH often.. Shaitaan wont disturb us.
Let us be fans of our Prophets and Sahabhas .. than anyone else..
I like to share a hadith here... found from a post in IB...
Umar bin Al-Khattab asked the permission of Allah's Apostle to see him while some Quraishi women were sitting with him, talking to him and asking him for more expenses, raising their voices above the voice of Allah's Apostle.
When 'Umar asked for the permission to enter, the women quickly put on their veils. Allah'› Apostle allowed him to enter and 'Umar came in while Allah's Apostle was smiling, 'Umar said "O Allah's Apostle! May Allah always keep you smiling." The Prophet said, "These women who have been here, roused my wonder, for as soon as they heard your voice, they quickly put on their veils. "'Umar said, "O Allah's Apostle! You have more right to be feared by them than I." Then 'Umar addressed the women saying, "O enemies of yourselves! You fear me more than you do Allah's Apostle ?" They said, "Yes, for you are harsher and sterner than Allah's Apostle." Then Allah's Apostle said, "O Ibn Al-Khattab! By Him in Whose Hands my life is! Never does Satan find you going on a way, but he takes another way other than yours."
-Sahih Bukhari
