Al Sufian

1	O you who believe! Let it be said: Al-Wakil;
2	The Trustee, the Dependable, the Advocate;
3	And the ninety-fourth name of Allah, the One, the Absolute, the Almighty.
4	The merchants and moneylenders say that a vow or covenant can be broken;
5	If it be with foreigners and if homage is paid to their demon gods.
6	The deceptive moneylenders claim that if an Agreement is made with an unworthy suitor,
7	Then they make deny the agreement if they choose.
8	The Christians on the other hand have shown themselves to be no better than the moneylenders and merchants,
9	When they demand the right to change agreements and price, based on superior position, not honor.
10	Thus people are weary of agreements,
11	And so fewer people engage in agreements in the event that the other side fails to honor their part.
12	This is not The Way.
13	Agreements that are valid are firstly offered to Allah and then the men and women who make them.
14	All valid agreements must be kept if one is to honor The Way of Islam and the laws of Allah.
15	To deliberately break an agreement is therefore a great transgression against Allah.
16	Allah does not permit agreements to be broken.
17	The word of a man is his bond.
18	It is sufficient that a man declare himself to be of the Way of Islam,
19	Then to give his solemn word,
20	Rather than any manuscript be needed to witness the fact.
21	Thus, a true Muslim always keeps his word.
22	Verily, any man who cannot keep his word cannot be a Muslim.
