dawat-us-salafiyyah:

Ibn Taymiyyah:

“The reason why the religion of Allah and its rituals are vanishing, and kufr and sin are prevailing, is because of imitation of the kaafireen, just as the means of preserving all good is by following the ways and laws of the Prophets.”

(al-Iqtidaa’, 1/413)

,,

The one who does not perform his obligations is actually worse than the one who performs sins. Anyone having some knowledge about the revelation of Allah, the guidance of the Prophet and the life of the companions would see that those who are pointed at today as the most pious people as in fact the least pious… Indeed, what deen and what good is there in a person who witnesses the sanctities of Allah سبحانه وتعالى being violated, His Hudood not applied, His religion abandoned, the Sunnah of His Messenger shunned, and yet remains still with a cold heart and a silent tongue - a dumb Shaitan. In the same way the one who talks falsehood is a speaking Shaitan. Isn’t the misfortune of Islam due only to those who whenever their food and positions are secure, would not care about what happens to the religion? The best among them would offer a sorry face. But if there was a shortcoming in one of the things their heart is attached to like their rank or money, they would sacrifice and strive and strain and struggle and use the three levels of prevention (their hands, tongues and hearts, as mentioned in the famous hadith) according to their capability. These people, besides deserving the anger of Allah, are afflicted with the greatest calamity without even knowing it: They have a dead heart. Indeed the more alive a person’s heart is, the stronger its anger for the sake of Allah and the more complete his support to Islam and Muslims
