Allah commands believers to get sustenance by the lawful job and the lawful path, and to eat good things. Islam is based on purity in entirety. Allah Almighty says in the Quran:
''O people! Eat of what is lawful and good on earth, and do not follow the footsteps of Satan. He is to you an open enemy.'' (Surah al-Baqarah, 168)
In this ayah, Allah urges not only the believers but all people to eat the lawful and good things. Allah gives the general permission for His earthly servants to eat of the lawful and good things He has created for them. There is no need to list the halal and good blessings by name. Because there are many of them.
