Regarding the part of the hadith which mentions, “ The musk seller shall either give you fragrance, you shall purchase some from him, or at the very least, fragrance will come your way”;  Mufti Aḥmad Yār Khān writes:

This describes the minimum benefit. Buying musk or receiving it as a gift is the greater benefit, which provides ongoing advantage, while only receiving fragrance is a lesser benefit.

Remember, enemies of the Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم, such as Abū  Jahl and others, never came into the Prophet’s presence. Such an honour is attained only through love.

Another part of the hadith mentions, “As for the blacksmith, he shall either burn your clothing or you shall find unpleasant smell emanating from him.” Commenting on this, Mufti Aḥmad Yār Khān writes:

This teaches us to avoid bad company as much as possible, as it ruins both one’s religion and worldly life, whilst good company secures one’s religious and worldly matters. Being around a snake can take your life, whilst being around a bad friend can destroy your faith.^[1]

Bad company can ruin one’s faith

Imam Muhammad b. Aḥmad Dhahabī رَحْمَةُ الـلّٰـهِ عَـلَيْه said:

There was a man who used to sit with alcoholics. When his death drew near, somebody encouraged him to recite the kalima. Instead of reciting it, he said, “You drink and let me drink too.” معاذاللہ  He died without reciting the kalima.

If this was the fate of merely sitting with people who drink alcohol, imagine the consequences of drinking alcohol itself.^[2]
