The people used to sell camels on the basis of Habal-al-Habala. The Prophet (ﷺ) forbade such sale. Nafi` explained Habal-al-Habala by saying. "The camel is to be delivered to the buyer after the she-camel gives birth."
Sahih al-Bukhari Book 35, Hadith 16
← Previous Hadith Abu Burda and `Abdullah bin Shaddad sent me to `Abdur Rahman bin Abza and `Abdullah bin Abi `Aufa to ask them about the Salaf (Salam). They said, "We used to get war booty while we were with Allah's Messenger (ﷺ) and when the peasants of Sham came to us we used to pay them in advance for wheat, barley, and oil to be delivered within a fixed period." I asked them, "Did the peasants own standing crops or not?" They replied, "We never asked them about it."

Sahih al-Bukhari Book 35, Hadith 15 Next Hadith → Allah's Messenger (ﷺ) gave a verdict regarding Shuf'a in every undivided joint thing (property). But if the limits are defined (or demarcated) or the ways and streets are fixed, then there is no pre-emption.

Sahih al-Bukhari Book 36, Hadith 1
