Rabee-ul-Awwal 12 (Arabic Hijri Calendar) is the day, the leader of the Muslim Community, Prophet Muhammed (Peace Be Upon Him) born. The same day after 63 years he ascended from the world. We praise His thrive to bring peace into a Dark Aged world then. It was then people hated to have baby girls born. They were ashamed of it. They even burried them alive to hide their dignity among the others. When Islam descended on Prophet Muhammed, who, then was a honesty little lad doing the right thing and helping the poor ones, he tried his best to gather people to Islam and bring peaceful atmosphere among the evil society. Later, when God gave the permission to fight for their lands and wealth, Prophet Muhammed (s) led the society with courage and understanding. There were lots of dos and donts in their battles. To only fight against the army and not women, old people, children. Do not even destroy any trees or animals. Any houses or water sources. Fight with rules. Amid the wars they won, they freed the enslaved after a while. The slaves were delighted to see how beautiful the religion they were against was. Thousands converted to Islam and embraced the world of happiness and equality.
And as per this year it's December 12, the day He came to us and left us.
