A man who marries a woman and stipulates to her: only what I allot you by night or day

Al-Hakam and Hammad were asked: If a man, in marrying a woman, stipulates that she will be content with whatever share of night or day he allots her, what is the ruling? They said: This is an invalid condition.

Al-Zuhri, concerning a man who stipulates in marriage that he will not come to her for such-and-such (a time) and will spend on her only a fixed amount, said: The settlement which is commanded in the Qur'an is only after consummation. And he used to dislike this.

Yunus was asked about a condition stipulated in marriage. He said: Al-Hasan saw no harm in it if it was made openly.

And Ibn Sirin used to dislike stipulating it at the outset (of the marriage), and saw no harm in it after that.

Jabir said: I asked Amir about a man who has a wife, then marries another woman and stipulates one day for this one and two days for that one. He said: There is no harm in it.
