In Zeiarat Ali Akbar sermon which is narrated from Abi-Hamza Althumali said: Imam Alsadeq (AS) told him: Put your cheek on his grave and say 'Peace be upon you O Aba-Alhasan' three times. (2)

This nick name might be used to optimize for a good boy. also it might be happened because he got a boy called (Alhasan) and Imam Alsadiq (AS) in the same Zeirat sermon when it says: (Peace be upon you, your progeny, your family, your fathers, your sons, and your mothers; the righteous whom Allah intends only to remove from you the impurity , O people of the household, and to purify you with purification. The word –Sons- is a plural which means Ali Alakbar has more than two sons. Also his saying (AS) - , your progeny- refers to it too because a man's progeny is his offspring. If he is without offspring then there is no need to use this term (progeny). The receipt of this sentence from the tongue of the Imam who is the most knowledgeable in secrets of rhetoric and all requirements of the conditions are the hardest proofs on it. And it is clear that tradition narrated by the esteemed Sheikh Ibn Qulaweh in (Kamel Alzeiarah) with true bail and trusted narrators.
