Abu Kuraib did not make any mention of the stipulated time.
Ibn 'Umar (RA) reported: We used to buy foodgrains during the lifetime of Allah's Messenger (ﷺ) . He (the Holy Prophet) would then send to us one who commanded us to take them (the foodgrains) to a place other than the one where we had bought them before we sold it.

Abu Hurairah (RA) (Allah be please with him) is reported to have said to Marwan: Have you made lawful the transactions involving interest? Thereupon Marwan said: I have not done that. Thereupon Abu Hurairah (RA) (ﷺ) said: You have made lawful the transactions with the help of documents only, whereas Allah's Messenger (ﷺ) forbade the transaction of foodgrains until full possession is taken of them. Marwan then addressed the people and forbade them to enter into such transactions (as are done with the help of documents). Sulaiman said: I saw the sentinels snatching (these documents) from the people.
Jabir bin'Abdullah (RA) reported Allah's Messenger (ﷺ) as saying: When you purchase foodgrains, do not sell them until you have taken possession of them.
