Very interesting for me to be able to read one Muslim scholar's short selection of the most important Hadith, presumably a taster of the kind of thing contained in the rest. Really helpful.
Loved this one:
"Whoever can guarantee to me what is between his jaws and what is between his legs, I will guarantee Paradise to him." (Saheeh al-Bukhari, 6474).
This one is pretty conclusive too:
"No one who has an atom's weight of pride in his heart will enter Paradise" (Saheeh Muslim, 91)
Not looking good for humanity then...
