The Baghdad Islamic Bank sold on a murabaha basis a house to Imam Ghazali at a markup of 8% per annum constant rate of return to be paid over 10 years in equal annual instalments. The cost of the house was 50,000 dinars and Imam Ghazali paid 10,000 dinars as deposit. Baghdad Islamic Bank follows Islamic accounting Standards and recognises profits according to instalments due. Imam Ghazali paid the instalments for the first 2 years but was late in paying the 3rd instalment by one month (which he paid together with the tawid). The bank charged him ta’wid 10 dinar, which would be payable to charity. At the end of the 4th year, the Khalifa Harun Al Rashid gifted Imam Ghazali, a bounty for his magnum opus ‘Ihya ulumuddeen’ of 60,000 dinars. The Imam decided to redeem his house financing, keep a balance of 10,000 dinars for his expenses, and give the balance as sadaqah to achieve the pleasure of Allah swt. Baghdad bank gave him a full rebate on the unearned profits for the remaining period of the original murabaha contract, which was redeemed on the last date of the 4th year. Alhamdulillah, the Imam was able to give the intended amount of the sadaqah in Ramadhan as the moon was sighted on the last day the 4th year of the murabaha contract. How much sadaqah did he give?
