Hasan says that there is pre-emption only in land.

Hazrat Shurayh says that there is pre-emption (shuf‘a) in a jarib (a specific measure of land) and in land.

Ibrahim also says the same.

It is narrated from Hazrat Ibn Abi Mulaika that the Holy Prophet (peace be upon him) decreed the right of pre-emption (shuf‘a) for everything, including land, houses, female slaves, and male slaves. Hazrat Ata said: There is shuf‘a in land and houses. Hazrat Ibn Abi Mulaika said: Are you listening to me that I said the Messenger of Allah (peace and blessings be upon him) said this, and yet you are saying this?

24236 - He said: Ata said: "Pre-emption (shuf‘a) is only in land and houses." Ibn Abi Mulayka said: "Do you hear me—may you lose your mother—saying: 'The Messenger of Allah صلی اللہ علیہ وسلم said,' and then you say something like this?"
