Abu Dawud said: Another version says: He asked him about the period until he reached the period of seven days. The Messenger of Allah (ﷺ) replied: Yes, as long as you wish (i.e. there is no time limit).
Abu Dawud said: There is a variance in the chain of narrators of this tradition. The chain is not strong.
Another chain from Yahya b. Ayyub is also disputed.
