It is mentioned in a reliable tradition that Imam al-Baqir said,
“After ‘Isa was born he grew up speedily. In one day he grew as much as others grow in two months. When he was seven his mother took him to a school and seated him in front of the teacher. The teacher said bismillah hir rahman nir raheem (In the name of Allah, the Beneficent, the Merciful) and ‘Isa at once repeated the words.
Then the teacher asked him: say ABJAD. ‘Isa raised his head and asked the teacher whether he knew the meaning of ABJAD? The teacher picked up a lash to hit him. ‘Isa said, ‘O teacher! Do not hit me. If you know the meaning tell it to me otherwise ask me to describe it.’ The teacher said, ‘Describe it.’ ‘Isa, ‘A (Alif) is AALAA meaning the bounties of Allah, B is for BAHJAT meaning ‘GRACE’ and Divine Attributes, J is for (Jamaal e Ilaahi), D that is Daal is for Deen e Ilahi (religion), H (hey) stands for Haul (hell), V (vaav) indicates VAIL LI AHLIN NAAR which means woe unto the dwellers of Hell, Z (Ze) points to Zafeer which indicates the screaming of sinners in the hell and the bursting of hellfire, Huttiya shows that sins are washed away by Istgfaar, KALMAN is ‘Kalma e Khudaa’ (words of Allah) and that nobody can alter His words and figures, SA A FA SA means the Resurrection Day (Dooms day of Final Judgment) which will exhibit tit for tat (perfect justice will be given to all by exact measure) QRESHAT means all will be made to sleep in the grave and will be resurrected on the Day of Judgment.’ Hearing all this, the teacher told the lady to take away her son as he possessed divine Knowledge and needed no teachers.”
