The Prophet (ﷺ) said, "Whoever takes the money of the people with the intention of repaying it, Allâh will repay it on his behalf, and whoever takes it in order to spoil it, then Allâh will spoil him." [3:572-O.B]

Once, while I was in the company of the Prophet (ﷺ) he saw the mountain of Uhud and said, I would not like to have this mountain turned into gold for me unless nothing of it, not even a single Dinâr remains of it with me for more than three days (i.e. I will spend all of it in Allâh's Cause), except that Dinâr which I will keep for repaying debts." Then he said, "Those who are rich in this world would have little reward in the Hereafter except those who spend their money here and there (in Allâh's Cause), and they are few in number." Then he ordered me to stay at my place and went not far away. I heard a voice and intended to go to him but I remembered his order, "Stay at your place till I return." " On his return I said, "O Allâh's Messenger (ﷺ)! (What was) that noise which I heard?" He said, "Did you hear anything?" I said, "Yes." He said, "Jibrael [Gabriel ()] came to me and said, 'Whoever amongst your followers dies, worshipping none along with Allâh, will enter Paradise." I said, "Even if he did such and such things (i.e. even if he stole or committed illegal sexual intercourse), "he said, "Yes." 13-573-0.B]

I went to the Prophet (ﷺ) while he was in the mosque in the forenoon. The Prophet (ﷺ) told me to pray two Rak'at. I owed some debt from him. He repayed me the debt and gave me an extra amount. [3:579-O.B]

The Prophet (ﷺ) said, "I am closer to the believers than their ownselves in this world and in the Hereafter, and if you like, you can read Allâh's Statement: ' The Prophet (ﷺ) is closer to the believers than their ownselves. ' (V.33:6) So, if a true believer dies and leaves behind some property, it will be for his inheritors (from the father's side), and if he leaves behind some debt to be paid or needy offspring, then they should come to me as I am the guardian of the deceased." [3:583, 584-O.B]
