Sura Āl-ʿImrān 3:160

إِن يَنصُرْكُمُ ٱللَّـهُ فَلَا غَالِبَ لَكُمْ وَإِن يَخْذُلْكُمْ فَمَن ذَا ٱلَّذِى يَنصُرُكُم مِّنۢ بَعْدِهِۦ وَعَلَى ٱللَّـهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

in yanṣurkumu allāhu fa-lā ghāliba la-kum wa-in yakhdhulkum fa-man dhā alladhī yanṣurukum min baʿdihi wa-ʿalā allāhi fa-l-yatawakkali l-muʾminūna

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.

Sura al-Isrāʾ 17:22

لَّا تَجْعَلْ مَعَ ٱللَّـهِ إِلَٰهًا ءَاخَرَ فَتَقْعُدَ مَذْمُومًا مَّخْذُولًا

lā tajʿal maʿa allāhi ilāhan ākhara fa-taqʿuda madhmūman makhdhūlan

Take not with Allah another object of worship; or thou (O man!) wilt sit in disgrace and destitution.

Sura al-Furqān 25:29

لَّقَدْ أَضَلَّنِى عَنِ ٱلذِّكْرِ بَعْدَ إِذْ جَآءَنِى وَكَانَ ٱلشَّيْطَٰنُ لِلْإِنسَٰنِ خَذُولًا

llaqad aḍallanī ʿani l-dhikri baʿda idh jāʾanī wa-kāna l-shayṭānu lil-insāni khadhūlan

"He did lead me astray from the Message (of Allah) after it had come to me! Ah! the Evil One is but a traitor to man!"
