The biggest problem, now in the world is person who we can follow.
The crisis bigger than crisis of energy, health, food, transportasion and water. Because without a leader who he is visioner, competen and has high integrity, so the problems more than serious.
Now we have not the good model who we can follow.
But, one person who has drawed in Qur'an and Sunnah, Muhammad SAW is perfect person as a good model to teach us how to life. How to self development, business, lead to family, dakwah, social & politics, education, legal system abd military. All of that we can follow.
Narrated Abu Hurairah RA : The Prophet SAW said, "Allah did not send any Prophet but he shepherded sheep. "His Companions asked him. "Did you do the sama? "The Prophet SAW replied, "Yes, I used to shepherd the sheep of the people of Makkah for some Qirat." (Sahih Al-Bukhari)
