If a person works with the father in the shop and all the entire empire is built by father's contribution only after a period of more than 40 years, and the person steals a huge amount from the funds of shop and go for Umrah and Hajj every year and also conceals so many facts about the funds of the business from his other brothers as well and keeps all the stolen amount at the particular place hiding from his entire family members including his brothers, sisters, mother and father then I want to ask that will Allah accept his prayers and Hajj and Umrah which he performs every year, and what types of torment will come on him from Allah for doing such kind of acts.
بسم الله الرحمن الرحيم
The Hajj or Umrah performed with haram money do not carry reward. However, if someone does fardh Hajj, it shall be fulfilled. It should be noted that accusing anyone of doing Hajj with stolen money shall only be correct when it is supported by Shariah evidence, otherwise it is not lawful to blame someone merely by supposition. The holy Quran and Hadith ask us not to have suspicion about any person.
يَا أَيُّهَا الَّذِينَ آمَنُوا اجْتَنِبُوا كَثِيراً مِّنَ الظَّنِّ [الحجرات : 12]
وقال عليه السلام فى حديث طويل: وأن نظن به ظناً سيئاً (مجمع الزوايد: 2/292)
In the above mentioned case, the claims of stealing, concealing the fact regarding the business fund and performing Hajj and Umrah with stolen money are neither clear nor proved with Shariah evidence; hence it shall not be lawful to label the above mentioned ruling on the said person without Shariah evidence.
Allah knows Best!
