Halal and Haram Earnings, Bank Accounts, and Financial Dealings in Islam

(1) Father’s Salary and Increment Error

• Neglecting office duty: If someone spends around 40% of office hours on personal work, this is negligence and a violation of trust.
• Extra increment due to clerical error: If a clerical mistake results in an additional increment and the person knowingly continues receiving 400–500 extra every month, this portion is doubtful/haram income.

Ruling:
✔ If higher officials are aware and still allow the salary, it is considered halal.
✔ If they are unaware, then approximately 40% will be haram and the rest halal.
✔ For the son (Zayd), taking monthly allowance or expenses from this income will be halal only to the extent of the halal portion.
✔ Eating at home and using provisions is permissible if the majority is halal; otherwise, caution is required.

(2) Earnings of a Brother Working Abroad

• He lied initially (about study leave, and at the airport claiming tourism). This was sinful and requires tawbah.
• If his present job as a doctor is lawful and he fulfills duties honestly, then the salary is halal.
• Money sent to parents and family is halal for them.

(3) Keeping a Non-Interest Bank Account

• Even if the account itself is non-interest, the bank is an interest-based institution.
• Qur’ān: ﴿وَلاَ تَعَاوَنُوْا عَلَى الْإِثْمِ وَالْعُدْوَانِ﴾
  “Do not help one another in sin and transgression.”
• Thus, keeping money in the bank without need is considered cooperation in sin.
• If no major risk of theft exists at home, keeping funds in a bank is impermissible.

(4) Sending Money Through the Bank

• If Zayd (abroad) sends halal earnings through the bank into Bakr’s account:
  ✔ The money itself is halal for Bakr.
  ❌ However, maintaining a bank account remains sinful due to involvement with interest-based institutions.

(5) Mixing of Halal and Haram Income

• If halal and haram wealth is mixed, then:
  ✔ The exact haram amount must be separated and returned to the rightful owner or spent in a lawful charitable cause.
  ✔ The remainder is halal.

(6) Mixing of Halal and Haram Money in a Bank Account

• If an account has 500 haram rupees and later halal money is added:
  ✔ Withdrawing with intention to take only the halal amount does not remove the sin.
  ❌ Twofold sin occurs:
  1. Consuming haram.
  2. Maintaining a bank account in a riba-based system.
     ✔ However, the money sent by Bakr from abroad remains halal as long as it is withdrawn separately with the correct intention.

Conclusion

◈ Salary must be free from negligence and unlawful increments.
◈ Initial lies require repentance, but lawful jobs produce halal earnings.
◈ Bank accounts in riba-based systems are impermissible unless in dire necessity.
◈ Mixing halal and haram wealth requires purification by removing the unlawful part.
