Frankly speaking, I feel that Khir Toyo has breached the moral grounds as a Muslim leader by underpaying his fellow Muslim for such a prime landed property.
Even if it is said that it was a willing seller and willing buyer thingy, there is such a condition where a Muslim must not misappropriate the property of his fellow Muslim or even that of a disbeliever by making a payment way below the market price as has been the facts of this case.
Allah Subhanahu Wa Ta'ala clearly warns us against misappropriating another's property unjustly as revealed in Surah Al Baqarah Chapter 2 Verse 188 :
TransliterationWala ta/kuloo amwalakumbaynakum bilbatili watudloo biha ilaalhukkami lita/kuloo fareeqan min amwali annasibil-ithmi waantum taAAlamoon
Sahih InternationalAnd do not consume one another's wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful].
It is so crystal clear that in the case of Khir Toyo knowingly buying his brother Muslim's property way below the market price is a crime that will be punished by Allah Azza Wa Jalla in the Hereafter.
One does not need to wait till a court decides otherwise. Surely one who was once the Menteri Besar @ Chief Minister of a state ought to know better than to short change his brother Muslim by such a preposterously huge amount or even any amount for the matter?
What is this earthly life if not a temporal stage of our existence as a servant of Allah?
All these worldly trappings and wealth will come to no good when our time is up and we are called to return to Him, the Malikul Mulk, Dzul Jalali Wal Iqram.
The best thing for Khir Toyo to do would be to re-compensate his brother Muslim with the difference of the purchase price according to the current market pricing and pay a penalty if the court so decides?
I wonder how one can sleep in peace knowing that one has committed such an obvious injustice against another and raise one's family in such an ill gotten abode?
May Allah grant us all a life that is free from such trials and tribulations.
