Assalaamu alaikum ZZZ,
(big smile) I'm happy to hear that you've found a house that seems to be good for you!
(sigh) Yes, I've had trouble with a local sheikh on a monetary matter, also. He was recommended to me, and he is well-respected and gives khutbahs in local masaajid, and runs umrah and hajj trips. But he is not a trustworthy person.
I think what I have learnt is that, as it says in the Qur'an, we really should draw up legal documents whenever there are financial transactions, and that we need witnesses with heft, no matter who the person you are transacting with is.
I have also learnt that it is necessary to fight, sometimes. That patience and gentleness is wrongly applied when there is wrongdoing. (mildly) I do not like to fight. Frankly, I like to have good relations with everyone. (smile) So Allah, in His Wisdom, Decided to test my sabr (self-restraint) in a different way. I had to restrain my desire to please and be liked, and insist on my rights.
(smile) And I did get the money back. (sigh) But yes, it had an effect against me with some people. (pensively) But it also contributed to the opening my eyes, to discovering who are genuinely good people, and who are not. (smile) It is nice to find good people. And, given that our time on this earth is limited and needs to be used to its maximum, it is also helpful to know who not to spend your time with. (smile) As the Prophet (SAWS) taught us, who we spend time with influences us.
(smile) Anyway, ZZZ, I pray you will recover the monies you need to buy your house. And that the road you must tread in trying to retrieve it may bring you closer to Allah (SWT).
May Allah, the Firm, Strengthen us when we enjoin good or hinder wrongdoing.
