Abu Dawud has stated: "From this book of mine four
Hadith are sufficient for an intelligent and insightful person. They are: • Deeds are to be judged only by intentions. • Part of a man's good observance of Islam is that he leaves alone that which does not concern him. • None of you can be a believer unless you love for your brother that which you love for yourself. • The permitted (
halal) is clear, and the forbidden (
haram) is clear, between these two are doubtful matters. Whosoever abstains from these doubtful matters has saved his religion." ==Works==
