Marriage is part of the sustenance that Allah has apportioned among His servants, and the servant takes the means that lead to it while relying upon Allah.

Question:
In her second question, she says: I am asking about the apportionment and the share in marriage. Is marriage an apportionment and a share, or is it the individual who determines and chooses his life partner? And is the servant the cause of rejection, as they say that the servant is the cause? If a girl is delayed in marriage and reaches the age of thirty-five or forty years or more and does not get married, is that related to the apportionment and the share, or not?

Answer:
There is no doubt that marriage is named by Allah (Glorified and Exalted is He) and is part of the divine decree, but the servant must exert the means. He should seek a righteous wife, and likewise the wife's guardian should seek for her a suitable and righteous match. This is part of exerting the means. As for the outcome of affairs, and whether harmony is achieved between the spouses or there is discord, that is in the hand of Allah (Glorified and Exalted is He). This is in the hand of Allah. As for the woman, or her guardian, or the husband, if they exert the means to which the Prophet (peace and blessings be upon him) guided, they have done what they were commanded to do and what they are able to do. As for the results, they are with Allah (Glorified and Exalted is He). However, we see, with Allah's permission, that if the means are exerted and the Sunnah is followed, Allah grants success to the spouses, success in a righteous marriage and good treatment. Yes.
