1.         If a person gets Haraam wealth and gives it in charity, it is not accepted. If he spends it, there is no blessing for him in it; and if he leaves it after death, it is a means of him entering Hell.

(Musnad Imam Ahmad, vol. 2, pp. 34, Hadees 3672)

Disaster for the person who performs Hajj with Haraam money

On page 541 of Fatawa Razawiyyah, volume 23, A’la Hadrat, Imam-e-Ahl-e-Sunnat, Maulana Shah Imam Ahmad Raza Khan رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has stated: The righteous act performed with usury (interest) money is not worthy of being rewarded. It is stated in a blessed Hadees: When the one who leaves to perform Hajj with Haraam earnings utters ‘لَبَّیْک اَللّٰہُمَّ لَبَّیْک’, a voice from the Ghayb (hidden) replies, ‘Neither your Labbayk is accepted nor is your service accepted, and your Hajj is rejected. (Ithaf-us-Sadah, vol. 4, pp. 727)

Until you return the Haram earnings that are in your possession to the deserving people . It is stated in another blessed Hadees: The Holy Prophet  صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated, ‘اَيُّهَا النَّاسُ اِنَّ اللهَ طَيِّبٌ لَا يَقْبَلُ اِلَّا طَيِّبًا’ O people! Undoubtedly Allah عَزَّوَجَلَّ is Pure, He عَزَّوَجَلَّ only accepts that which is pure[1].’

In one of his Kalams (poetic stanzas), Shaykh-e-Tareeqat, Ameer-e-Ahl-e-Sunnat دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـه advises the Muslim Ummah to abstain from the evil effects or curse of Haraam earnings:

نارِ دوزخ میں نہ لے جائے کہیں مالِ حرام

کر لو توبہ چھوڑ دو اے بھائیو !سب ہَیر پھیر

صَلُّوۡا عَلَى الۡحَبِيۡب       صَلَّى اللّٰهُ تَعَالٰى عَلٰى مُحَمَّد

Dear Islamic brothers! Surely, the consequences of the curse of Haraam earnings are extremely dangerous because it not only destroys the noble acts
