Rahim operates his Furniture business from a building taken on a monthly rent of RO 4000 from Khalid since January 2018. The agreement notifies that the rent has to be paid to Khalid every three months and that it will increase every year by 5%. Rahim paid all rental dues for 2018 but at the same time informs Khalid that he is having financial difficulties and needs money to buy Furniture for his business. Khalid agrees for the same and tells orally that he will let off paying the increase of 5% rent for 2019. Rahim was pleased with this and spent all the money to buy Furniture. In March 2019, when he paid rent Khalid demands the additional 5% towards increase in rent. When Rahim refers to their earlier conversation, Khalid tells that the agreement is clear with the clause of 5% increase of rent each year. He also specifies to comply as per the agreement signed by both the parties earlier. Rahim disputed and claimed as breach of the contract.
