The Wisdom Of Luqman
Luqman is not generally believed to be a Prophet, but he was a man who had been specially endowed with wisdom by Allah . He was the nephew of Prophet Ayyub (A) and lived at the time of Prophet Dawood (A). He was an extremely pious man and used to mostly remain silent while he pondered about the nature of life. Sometimes he would come to Prophet Dawood (A) to discuss problems.

One of Luqman's wives and some of his sons were disbelievers and so he preached to them about faith in Allah till they embraced Islam. His words of wisdom were worthy of being quoted in the Holy Qur'an, which says:
[And indeed We gave to Luqman wisdom, saying, "Be grateful to Allah; for whoever is grateful, verily he is only grateful for his own self; and whoever is ungrateful, (it is to the discredit of his own self) then verily Allah is Self-Sufficient, the Most Praised." And when Luqman said to his son while he counselled him, "O my son! Do not associate anything (in authority) with Allah, for verily associating (anything) with Allah is the greatest sin."
And We enjoined man concerning his parents; his mother bears him in weakness upon weakness and his weaning takes two years. Be grateful to Me and unto your parents, (and remember that) unto me is the ultimate return.
"O my son! verily if it is even the very weight of the grain of a mustard seed (closed) in (even) a rock, or (be it high) in the heavens or (buried deep) in the earth, Allah will bring it to light; Allah is All-Subtle (Lateef), All-Aware. O my son! Establish prayer and enjoin the good and forbid the evil, and be patient against what befalls you; verily this is the task of steadfastness. And do not turn your face to people (in scorn) and do not walk proudly in the earth; verily Allah does not like any self-conceited boaster. And be moderate (modest) and lower your voice; verily the most unpleasant of voices is the braying of the donkeys."

Quran 31:12 - 14, 16 - 19]
Luqman lived for 1,000 years from the time of Prophet Dawood (A) to that of Prophet Yunus (A). His life was and words are a great lesson in Akhlaq (morals) for mankind.
