Do injustices committed against people stand in the way of Allah answering the supplications of a repentant person if he intends to return these injustices?

Question:
The questioner says: I am a young man to whom Allah granted guidance, and all praise is due to Allah. I have committed injustices against some of my relatives, which are moneys I stole from them. I intend, if Allah wills, to return them once I have this amount available. The question is: Do these injustices stand in the way of Allah answering my supplications?

Answer:
These injustices do not prevent the acceptance of supplication, but they remain upon you; they remain in your liability. So either you settle them in this world, or you seek forgiveness from their owners. Or they remain upon you until the Hereafter, and you will be held accountable for them. So you should take the initiative, as much as possible, to pay them to their owners, or seek their forgiveness, or record them in papers for yourself, saying, "These are the rights of so-and-so, so-and-so, and so-and-so," so that you may remember them and pay them, or if you die, they may be paid from your estate. Write them down and acknowledge that they are the rights of so-and-so, so-and-so, and so-and-so.
