Question: How long after marriage is a women allowed to get married in Islam?
Answer: Assalamu alaikum,
I hope that you are well, insha’Allah.
It is permitted for a woman to re-marry after the completion of her waiting period (`idda).
What is the Waiting Period (`Idda)?
Legally, the woman is duty-bound to wait a period of time, after termination of a valid marriage contract (nikah), before re-marrying.
What is the basis for the Waiting Period (`Idda)?
The legal basis for the waiting period, or `idda, are the words of Allah, Most High: ‘Divorced women shall keep themselves waiting for three periods’ [2:228]  ‘Those among you who pass away and leave wives behind, their wives keep themselves waiting for four months and ten days’ [2:234]  ‘And those women from among you who have despaired of (further) menstruation, if you are in doubt, their `idda is three months, as well as of those who have not yet menstruated. As for those having pregnancy, their term (of `idda) is that they give birth to their child’ [65:4]
The Types of Waiting Period (`Idda)
From the Qur’anic bases, we understand that there are four types of waiting period (`idda).
 Three menstrual cycles: for the woman who has a regular menstrual habit;
 Three months: for the woman in menopause;
 Four months and ten days: if her husband passes away and she is not pregnant;
 Until she gives birth: if she is pregnant, regardless of whether the marriage ended by death of the husband or divorce;[Mawsili, al-Ikhtiyar li ta`lil al-Mukhtar; Maydani, al-Lubab fi Sharh al-Kitab]
However, there are legal details related to each type of waiting period and one would do well to consult a local scholar regarding one’s specific circumstance.
And Allah knows best.
