Getting married can save you from the two things that lead to hell.
The Prophet ﷺ said,
"Whoever can guarantee (the chastity of) what is between his two jaw-bones and what is between his two legs (i.e. his tongue and his private parts), I guarantee Paradise for him."
Marriage satisfies the needs of the private parts and prevents one from doing the haram, but how does marriage help with controlling the tongue? When you’re married, you have a responsibility to maintain that relationship with your spouse, and within that relationship, you have to be wise with your words. You have to think before you speak, which will prevent you from speaking ill or profanely, reducing the regret you will have.
I’ve seen plenty of brothers who run their mouths with no filter and are just at a level of immaturity you wouldn’t believe, and these people are usually single and have a high ego complex. Married men who work on their relationships know that the way you talk to men and the way you talk to women are two different things. Most of the time talking to women is actually just listening properly. It makes you more patient, and this also makes you more likely to process what you have heard before responding.
When you have children, it’s a whole different ballgame.
During the early months of fatherhood, men have reduced testosterone, increased estrogen, and increase bonding hormones as well. These are all part of Allah’s divine system, making men more empathetic now that they are a father, a nurturer. Of course this doesn’t mean you will turn into a female and your muscles will turn into fat. As a matter of fact, Alhumdulilah I have more muscle now than before I got married. These balanced increases and decreases in estrogen and testosterone during certain phases of a man’s life are part of what makes him a more wise individual.
A more merciful husband.
A merciful father.
The strictness and discipline comes out when needed, and the love and mercy also comes out when needed. It makes you think before you speak which sounds easy enough, but many people speak first and then ask questions later. The Prophet ﷺ was the perfect example of what to do when he wanted to address something to the community. If he ﷺ disliked something or what someone did, he would get angry and you could see the redness in his face, but he ﷺ didn’t lash out at his companions. His face would turn red, preparing the sahaba for what was to come, and then he would address the people.
It takes a lot of time and practice to get good at thinking before speaking, but getting married and having a family helps you develop these skills that you would otherwise be lacking in.
Does this excuse the brothers and sisters who aren’t married from having a bad attitude and running their mouths?
Of course not, just like it’s not allowed for them to have free rein with their private parts, they are not allowed to have free rein with their mouths.
But getting married, will certainly help you.
