Ibn Abbas (Allah be pleased with them) reported Allah's Apostle (may peace be upon him) as saying: If one among you lets out land to his brother, that is better for him than if he receives such and such (the definite thing). Ibn 'Abbis (Allah be pleased with them) said: It is Haql, and in the parlance of the Ansr it is Muhaqala.
