Good company. Good company is extremely important. There is a saying in Arabic that says “الصاحب ساحب” which roughly translates to the idea that a friend will pull you towards what they’re doing. Meaning, if you are going to befriend someone be sure they’re good people, because what ever they do will definitely; if not now, eventually influence you. Many will deny it, but it’s true and I’ve seen many examples of it.

Even the Prophet (pbuh) said: ” الرجل على دين خليله فلينظر أحدكم من يخالل” ‎[رواه أبو داود والترمذيُ بإسناد صحيح]

Translation: “A person is upon the religion of his close friend, so beware whom you befriend.” [Abu Daawood and At-Tirmithi]
So that shows you the importance of good company. Plus why would you ever want to expose yourself to rotten and toxic people who only do bad? That will not, nor will it ever benefit you as a person. Nothing good will ever come from bad company.

The Prophet (pbuh) said: “إنما مثلُ الجليسِ الصالح والجليسِ السوء كحامل المسك ونافخ الكير، فحاملُ المسك إما أن يحذيك، وإما أن تبتاع منه، وإما أن تجد منه ريحًا طيبة، ونافخُ الكير إما أن يحرق ثيابك، وإما أن تجد منه ريحًا خبيثة ” ‎[‏البخاري ومسلم]

Translation: “The case of the good companion and the bad companion is like that of the seller of musk and the blower of the bellows (iron-smith). As for the seller of musk, he will either give you some of the musk, or you will purchase some from him, or at least you will come away having experienced its good smell. Whereas the blower of the bellows will either burn your clothing, or at least you will come away having experienced its repugnant smell.” [Al-Bukhari and Muslim]

So ask yourself; is it worth being their friend if you lose yourself in the process? Think about it.
