Ismail Ax
Is this an Anagram perhaps? the letters make up the words “Mail Axis” and “ALIAS MIX” amoung other non-sensical words, those are the most clear... Odd.
Of course, you could continue to speculate why he might have chosen that particular gamer tag in the first place (assuming that's what it is)...
Islam does come to bear on this. He had the words: Ismail Ax written in red ink on one of his arms.
“Ibrahim went towards the temple armed with an ax. ....with his ax he destroyed all the statues except one, the biggest of them. He hung the ax around its neck and left.....Allah rewarded Sarah with a son, Ishaq in spite of her old age. Sarah prayed Allah to bless Hajar and Ibrahim with a child. And so came Ismail, a baby boy born to Hajar.”
