Let me remind you of the third kalima: سُبْحَان اللهِ وَ الْحَمْدُ لِلّهِ وَ لآ اِلهَ اِلّا اللّهُ وَ اللّهُ اَكْبَرُ وَلا حَوْلَ وَلاَ قُوَّة ِ الَّا بِاللّهِ الْعَلِىّ الْعَظِيْ (Flawless is Allah and the Praise is of Allah, and (there is) no god except Allah, and Allah is the Greatest. And (there is) neither might nor power except with Allah, the Sublime, the Tremendous.) Muslims today are weak because they don't practice their religion. They won't become strong by imitating the kuffar.
