Paradise whoever harbors even an atom’s weight of arrogance in his heart” (1); or, “Whoever cheats us is not one of us” (2); or, “Whoever claims descent from someone other than his father, or allies himself to anyone other than his patrons, Paradise is forbidden to him” (3); or, “Whoever deliberately swears a false oath in order to seize the wealth of a Muslim will meet Allah while He is angry with him” (4); or, “Whoever, by means of a false oath, deems it lawful to take the wealth of a Muslim—Allah has made the Fire obligatory for him and forbidden Paradise to him” (5); or, “A severer of kinship ties shall not enter Paradise” (6)—and there are many other hadiths of threat besides these.
It is therefore impermissible for us to single out a particular person who has committed one of these deeds and say, “This individual has incurred that specific threat,” for repentance and other causes that remove punishment remain possible.
