Robert and Jackson were lost in desert...they were dying of thirst when they came upon an oasis, and there was a Mosque...!
Robert to Jackson: "Look there is a mosque, lets pretend we are muslims, otherwise we'll not get any food or water...I am going to call myself 'Abdullah".
Willson refused to change his name and said: "my ...name is Jackson and i will never pretend to be other than but what I am!"
The Imam of mosque recieved both well and asked their names...
Robert: am Abdullah
Jackson: am Jackson
Imam turned to his helpers and said:
"bring some food for Jackson only"
And then Imam turned towards Robert and said:
"Ramzan Mubarak bhai Abdullah"
