Benefit: Importance of Choosing Companions Wisely
In the Name of Allāh, the Ever Merciful, the Bestower of Mercy
Answer: The ḥadīth is clear, that one’s companions leave behind an affect on him, so it is upon the Muslim to choose an upright friend who—through his companionship—will benefit him, make him stronger in his religion and (aid him in) avoiding bad companionship. The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said:
The example of the good and evil companions is like a bearer of musk and a person blowing a pair of bellows. As for the musk bearer, he either gives you some, or you buy from him, or at least you get a pleasant smell from him. As for the blacksmith, he either gets your clothes burnt or you get an unpleasant smell from him. [Ṣaḥīḥ al-Bukharī, Ḥadīth #2101].
Likewise, the saying of the poet:
If you (seek) companionship with the people then accompany the best of them. And do not accompany the corrupted lest that you spoil along with them.
Shaykh Ṣāliḥ ibn Fawzān al-Fawzān
