Imaaam Abdul-Azeez Bin Baaz (rahimahullaah) said:

So whoever wishes for victory and assistance from Allaah, and to make the word of (Allaah) uppermost, then he should change that which he is upon of disobedience, sins and opposition to the command of Allaah.   And your Lord has stated:

وَعَدَ ٱللَّهُ ٱلَّذِينَ ءَامَنُواْ مِنكُمۡ وَعَمِلُواْ ٱلصَّـٰلِحَـٰتِ لَيَسۡتَخۡلِفَنَّهُمۡ فِى ٱلۡأَرۡضِ ڪَمَا ٱسۡتَخۡلَفَ ٱلَّذِينَ مِن قَبۡلِهِمۡ وَلَيُمَكِّنَنَّ لَهُمۡ دِينَہُمُ ٱلَّذِى ٱرۡتَضَىٰ لَهُمۡ وَلَيُبَدِّلَنَّہُم مِّنۢ بَعۡدِ خَوۡفِهِمۡ أَمۡنً۬ا‌ۚ يَعۡبُدُونَنِى لَا يُشۡرِكُونَ بِى شَيۡـًٔ۬ا‌ۚ وَمَن ڪَفَرَ بَعۡدَ ذَٲلِكَ فَأُوْلَـٰٓٮِٕكَ هُمُ ٱلۡفَـٰسِقُونَ

‘Allaah has promised those among you who believe, and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the earth, as He granted it to those before them, and that He will grant them the authority to practise their religion, that which He has chosen for them (i.e. Islaam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me.'[24:55]

Allaah (subhaanah) did not say that He has made a promise to those who attribute themselves to the Quraish or the Arabs or those who build castles and excavate petroleum….rather Allaah tied this affair to true Imaan and righteous action-regardless whether they are Arabs or non-Arabs….[Source: Booklet Titled: Your Enemies Are About To Gather Against You: ‘The Causes Of The Weakness Of The Muslims In The Presence Of Their Enemy'(page:29-30)]
