Nasai

Hazrat Uthman ibn Maz'un radi Allahu anhu was a young man. He was very devoted in worship. He sought permission from the Prophet sallallahu alayhi wa sallam that they should remain constantly engaged in worship and not become entangled in matters concerning women, but the Prophet sallallahu alayhi wa sallam did not grant permission because this is against human nature. The true virtue lies in fulfilling the rights of Allah while maintaining human characteristics.

That is, we would make ourselves such that we would have no desire left for women at all, so that by remaining separate from the customs of marriage, we could devote ourselves solely to the worship of Allah.

Benefits and Issues:
➊
Hazrat Uthman bin Maz'un (radi Allahu anhu) had a great passion for worship.
He thought that by marrying and becoming occupied with the affairs of wife and children, the opportunities for voluntary worship—meaning voluntary prayers and fasting—would become fewer, so it would be better not to marry. However, the Messenger of Allah (sallallahu alayhi wa sallam) did not permit him to remain unmarried.
The noble Companions (radi Allahu anhum) would not do anything without first asking the Prophet (sallallahu alayhi wa sallam), because it is possible that an action may outwardly appear to be virtuous and seem very good, but in terms of the Shari‘ah, it may not be correct.
Innovation (bid‘ah) also outwardly appears to be a good deed, but one should not be deceived by its apparent goodness.
No matter how good an action contrary to the Sunnah may seem, it is necessary to avoid it.
The way to attain closeness to Allah is not to abstain from lawful things like the Hindus, yogis, or Christian monks, but rather, closeness to Allah is attained by acting upon the Shari‘ah’s instructions in matters of eating, drinking, and other affairs.
To deprive someone of masculine strength, or to attempt to deprive oneself of this strength, is prohibited in the Shari‘ah.
