From our master...
From our master, Imam al-Baqir (as), it has been related that he said: "The Prophet of Allah (S) has said, "There is no structure in Islam which is more loved by Allah (SwT) that that of marriage." In addition, our master, Imam Jafar as-Sadiq (as) has said, "Two Rakat of Salat of a married person is better than seventy Rakat of Salat of a bachelor and it is not good that marriage should be delayed due to poverty or other (material) needs…" It has been narrated from the Noble Prophet (S) that, "The person who delays marriage due to fear of poverty, or other such reasons has had negative thoughts about Allah (Glorified and Exalted is He)." May you all be successful and assisted (by Him).
It has been narrated from the Infallibles (as) that if a person marries, he has safe-guarded half of his religion and in other narrations, he has safe-guarded one-third of his religion. In this regards, there is no difference if this happens to be a person's first marriage or after separation from his spouse, he or she remarries.
In addition, if a person fears that by not getting married, one will fall into sin and transgression (of the laws of Allah), then it becomes obligatory upon one to get married. And Allah (SwT) knows best.
