وَإِذَا غَشِيَهُم مَّوْجٌۭ كَٱلظُّلَلِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ فَمِنْهُم مُّقْتَصِدٌۭ ۚ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا كُلُّ خَتَّارٍۢ كَفُورٍۢ
And if a wave enshroudeth them like awnings, they cry unto Allah, making their faith pure for Him only. But when He bringeth them safe to land, some of them compromise. None denieth Our signs save every traitor ingrate.
Surah Luqman(31:32)
Sahih al-Bukhari
Oneness, Uniqueness of Allah (Tawheed)
Chapter: “…In order that you may be brought up under My Eye.
Narrated Anas:
The Prophet (ﷺ) said, "Allah did not send any prophet but that he warned his nation of the one-eyed liar (Ad-Dajjal). He is one-eyed while your Lord is not one-eyed, The word 'Kafir' (unbeliever) is written between his two eyes."
Sahih al-Bukhari 7408
