He—may Allah have mercy on him—was also asked:

Concerning a man who co-owned a property with a witness. His co-owner then sold his share to another witness, ostensibly for a price far above its market value, while the two secretly agreed on the market price in order to defeat the right of pre-emption. Does the right of pre-emption lapse or not?

He replied:

It is unlawful to lie or resort to stratagems to nullify a Muslim’s right. If the co-owner requests it, the buyer must surrender the share subject to pre-emption at the price the two secretly agreed upon. If he denies him this, his religious integrity is called into question. The judge must uphold the right of pre-emption if he ascertains the true facts.
