Birth Anniversary of Hazrat Ali Akbar: The Day of Youths
Heartiest congratulations to you all on a very auspicious day commemorated as Day of Youths. It is the day that is celebrated every year in the Islamic Republic 
of Iran as the Day of the Virtuous Youths, for it was on this day on the 11th of the month of Sha’ban that God had granted the Martyr of Karbala, Imam Husain (AS), with a meritorious son, who bore a striking resemblance to his grandfather, Prophet Mohammad (SAWA) in both appearance and, as he grew up, in excellence of character. If you are ready we have prepared a special feature for you in this regard as motivation for all virtuous youths, please stay with us.
“That is the good news Allah gives to His servants who have faith and do righteous deeds! Say (O Prophet to mankind), ‘I do not ask you any reward for it (enlightening minds with Islam) except love of [my] nearest of kin…”
Birth of Imam Zayn al-Abidin(A.S.)
The world brightened when Ima`m Zayn al-‘Abidin, peace be on him, was born, for he would split the fountain of knowledge and wisdom in the earth. He would also show, through his behavior, wonderful examples of self-negation, renouncing the world, and cleaving to Allah. The Prophet’s family was very happy to receive this blessed baby, of whom the Prophet, may Allah bless him and his family, gave good news. All the companions who had good relations with the members of the house (ahl al-Bayt) were happy to hear of the birth of Ima`m Zayn al-‘Abidin.
Misfortunes and pain accompanied him from his childhood. Among them was that his pure mother died while he was still a baby in the cradle.
Birth of Al-Abbas (A.S)
“Peace be upon Ab al-Fadl al-Abbas, he preferred his brother to himself and sacrificed himself for his brother, supplied himself with opportunities of today for (the rewards of) the hereafter, hurried to supply the family of Imam with water, and his two hands were cut off during performing this task.” (Part of Ziarah Nahiah 
Muqaddasah)
