I have in the past been interested in this particular type of investment with the said previous mention brother. However I would like to as a Muslim first and then as a person who has many investments and business dealings request that clear contractual agreements are provided and executed that are will stand in the court of law. It is absolutely imperative that when money is exchanged that both parties are satisfied wholeheartly in the deal. It is further essential that it is made absolutely clear of exactly what is involved as part of this contractual agreement. It would be incorrect to state that there is no risk unless you have the halal insurance processes or make it clear that their is alternative security on the funds or there is not...... Anyhow not trying to rain on the parade. Sounds like an intriging venture and may Allah put barakah in this.
