أَمَّنْ هُوَ قَٰنِتٌ ءَانَآءَ ٱلَّيْلِ سَاجِدًۭا وَقَآئِمًۭا يَحْذَرُ ٱلْءَاخِرَةَ وَيَرْجُوا۟ رَحْمَةَ رَبِّهِۦ ۗ قُلْ هَلْ يَسْتَوِى ٱلَّذِينَ يَعْلَمُونَ وَٱلَّذِينَ لَا يَعْلَمُونَ ۗ إِنَّمَا يَتَذَكَّرُ أُو۟لُوا۟ ٱلْأَلْبَٰبِ
Is he who payeth adoration in the watches of the night, prostrate and standing, bewaring of the Hereafter and hoping for the mercy of his Lord, (to be accounted equal with a disbeliever)? Say (unto them, O Muhammad): Are those who know equal with those who know not? But only men of understanding will pay heed.
Surah Az-Zumar(39:9)

Oneness, Uniqueness of Allah (Tawheed)
Chapter: “…In order that you may be brought up under My Eye.
Narrated `Abdullah:
Ad-Dajjal was mentioned in the presence of the Prophet. The Prophet (ﷺ) said, "Allah is not hidden from you; He is not one-eyed," and pointed with his hand towards his eye, adding, "While Al-Masih Ad- Dajjal is blind in the right eye and his eye looks like a protruding grape."
