As for the saying that, getting married at an early age diverts from gaining knowledge and from studying, this is not the case. Rather, the opposite of this is correct because tranquility, peace of mind, and pleasure never cease to be obtained through marriage. These things help the student to reach his goal because, he has peace of mind, and his thoughts are not cluttered due to discomfort and this helps him study.
Now on the other hand abstaining from marriage in reality blocks whatever knowledge he wants to attain, because it is not possible to acquire knowledge in a state of confusion and anxiety. However, if he gets married, his mind is at rest and his soul is at ease. He gets a house to take as a shelter and a wife who relaxes and helps him. These things help him to attain knowledge.
If Allah makes it easy and this marraige becomes a source of comfot to become a relationship, then this is from among the things which make it easy for the student to pursue knowledge. Matrimony does not block the path to knowledge as some believe. For that reason, having children is an enormous blessing in this life and in the next.
