The condition of Arabia like at the time of the birth of Hazrat Muhammad (SM) was very bad. 

At the time of birth of great Prophet (S.) the people of Arab used to be engaged in murderous activities, looting, fighting, snatching away other’s belongings, enmity, robbery etc. in an unlimited, unhindered way. There was no security of life. There was nothing of Law and justice. Drinking wine, taking interest (Sud), gambling and other vices were their usual affairs of life. They forgot Allah, used to pray many idols made of clay. They placed many statues inside the holy Ka’aba. They installed 360 idols in the courtyard of Ka’aba. At that time people were sold in the market as slaves like goods. The owners of the slaves bought by them did inhuman torture on them all the time. There was no respect for woman, either in the family or in the society. Birth of a daughter- child was very insulting. They immediately after birth of a daughter, used to kill them (daughters) and dug deep under the soil. They did not show respect to Law and order. There were no misdeeds, which they did not do. In history, this period is called “Ayyam-e-Jaheliyat” or the “black period” the period of darkness.
Our beloved Prophet (Sm) was born in such an age and in such vulnerable condition of the society as a saviour of mankind and guide to the light and truth.

Thanks for your questions.
