In God's Name, the Merciful, the Compassionate.

According to Abu Daud these four Sayings of The Prophet contain the summary of Islamic law.

• Actions will be judged according to intentions.
• The proof of a Muslim's sincerity is that he payeth no heed to that which is not his business.
• No man is a true believer unless he desires for his brother that which he desires for himself.
• That which is lawful is clear, and that which is unlawful likewise, but there are certain doubtful things between the two from which it is well to abstain.
