Dua for freedom from Debts and Haram earnings:
وعن عليّ أنَّ مُكَاتباً جاءهُ فَقَالَ : إنِّي عَجِزْتُ عَنْ كِتَابَتِي فَأعِنِّي ، قَالَ : ألا أُعَلِّمُكَ كَلِماتٍ عَلَّمَنِيهنَّ رسُولُ الله لَوْ كَانَ عَلَيْكَ مِثْلُ جَبَلٍ دَيْناً أدَّاهُ اللهُ عَنْكَ ؟ قَالَ : قُلْ : « اللَّهُمَّ اكْفِني بِحَلاَلِكَ عَنْ حَرَامِكَ ، وَأغْنِنِي بِفَضْلِكَ عَمَّنْ سِواكَ » . رواه الترمذي ، وقال : ( حَدِيثٌ حَسَنٌ ) . فيه : استحباب الدعاء بهؤلاء الكلمات .
'Ali (May Allah be pleased with him) reported: A slave who had made a contract with his master to pay for his freedom, came to me and said: "I am unable to fulfill my obligation, so help me." He said to him: "Shall I not teach you a supplication which the Messenger of Allah (PBUH) taught me? It will surely prove so effective that if you have a debt as large as a huge mountain, Allah will surely pay it for you. Say: 'Allahumm-akfini bihalalika 'an haramika, wa aghnini bifadlika 'amman siwaka (O Allah! Grant me enough of what You make lawful so that I may dispense with what You make unlawful, and enable me by Your Grace to dispense with all but You)."
Commentary: It is important to recite this Du'a in order to seek Allah's Help in paying one's debts and in avoiding to beg of people.
« اللَّهُمَّ اكْفِني بِحَلاَلِكَ عَنْ حَرَامِكَ ، وَأغْنِنِي بِفَضْلِكَ عَمَّنْ سِواكَ »
