Choosing Righteous Companions

Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "The example of the righteous companion and the evil companion is like that of the musk-seller and the one who blows the bellows. As for the musk-seller, he will either give you some as a present, or you will buy some from him, or you will just receive a good smell from him. Whereas the one blowing the bellows will either burn your clothes, or you will receive a nasty smell from him.” [Al-Bukhari and Muslim].
