Second son of Fatima (SA) and Ali (AS) Hussain (AS) was born on 3rd Shabaan, 4th year of Hijri (10.1.626 AD) When he was born the Holy Prophet was given the news of the birth of his 2nd grandson. He arrived at the house of his daughter, took the little baby in his arms, said the Azan and Iqamah in his ears. People around the Prophet saw tears in his eyes. Fatimah asked what was the reason for this, he told her that this boy of hers will achieve martyrdom, but consoled her by adding that God will create a nation who will mourn Hussain till the Day of Judgement. Another famous saying of the Prophet at the same time became synonymous with the name of his grandson Hussain. “Hussian-o-Minni wa Ana Minul Hussain”. Hussain is from me and I am from Hussain. One can explain this Hadith that Hussain, being the grand son of the Prophet was from him biologically. How a grandfather was from his grand son needs to be explained. Prophets of God speak spiritually rather than materially. He was talking about Islam the Deen he was assigned by God to propagate God's religion.. He was for Islam and his whole life was for Islam and its establishment on earth. Any break in this mission would subvert this mission which was the purpose of his creation. The message of the Holy Prophet in this saying was that Hussain will, in some near future save this mission from destruction, hence the very purpose of his being will be saved by the sacrifice of his grandson. He was giving the news of a future occurrence. The story of Kerbala unfolds.
