" When you have taken a decision, put your trust in Allah. For Allah loves those who put their trust in Him. If Allah helps you, none can overcome you; if He forsakes you, who is after that that can help you? In Allah, then, let believers put their trust" (Surah Al-'lmran 3:159-160).
And remember the words of Allah: "And those who strive hard in Our Cause, We will certainly guide them to Our Paths, for verily Allah is with those who do right" (Surah al-Ankabut 29:69).
