Surah Aali Imran (The Family of Imran), Verse 160

اِنْ یَّنْصُرْكُمُ اللّٰهُ فَلَا غَالِبَ لَكُمْ وَاِنْ یَّخْذُلْكُمْ فَمَنْ ذَا الَّذِیْ یَنْصُرُكُمْ مِّنْ بَعْدِهٖ وَعَلَی اللّٰهِ فَلْیَتَوَكَّلِ الْمُؤْمِنُوْنَ ۟

Iny-yansurkumul laahu falaa ghaaliba lakum wa iny-yakhzulkum faman zal lazee yansurukum min ba'dih; wa 'alal laahi falyatawakkalil mu'minoon

“If Allah helps you, none can overcome you: If He forsakes you, who is there, after that, that can help you? in Allah, then, Let believers put their trust.”
