أَفَحَسِبَ ٱلَّذِينَ كَفَرُوٓا۟ أَن يَتَّخِذُوا۟ عِبَادِى مِن دُونِىٓ أَوْلِيَآءَ ۚ إِنَّآ أَعْتَدْنَا جَهَنَّمَ لِلْكَٰفِرِينَ نُزُلًۭا
Do the disbelievers reckon that they can choose My bondmen as protecting friends beside Me? Lo! We have prepared hell as a welcome for the disbelievers.

Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: How to present Islam to a (non-Muslim) boy
Narrated Ibn Umar:
(Later on) Allah's Messenger (ﷺ) (once again) went along with Ubai bin Ka'b to the garden of date-palms where Ibn Saiyad was staying. When the Prophet entered the garden, he started hiding himself behind the trunks of the date-palms as he wanted to hear something from the Ibn Saiyad before the latter could see him. Ibn Saiyad was lying in his bed, covered with a velvet sheet from where his murmurs were heard. Ibn Saiyad's mother saw the Prophet (ﷺ) while he was hiding himself behind the trunks of the date-palms. She addressed Ibn Saiyad, "O Saf!" (And this was his name). Ibn Saiyad got up. The Prophet (ﷺ) said, "Had this woman let him to himself, he would have revealed the reality of his case." Then the Prophet (ﷺ) got up amongst the people, glorifying Allah as He deserves, he mentioned Ad-Dajjal, saying, "I warn you about him (i.e. Ad-Dajjal) and there is no prophet who did not warn his nation about him, and Noah warned his nation about him, but I tell you a statement which no prophet informed his nation of. You should understand that he is a one-eyed man and Allah is not one-eyed."
