“...It’s not even clear how exactly his name is spelled. We’ve seen news reports referring to him as Malik Nadal Husan, Malik Nidal Husan, Malik Nadal Hussan, Malik Nidal Hussan, Nidal Malik Husan, and Nidal Malik Hussan.”
Hussan eh? One vowel short of Hussain?
Since Arabic does not use the Latin alphabet, there can be many spellings. Look at Usama/Osama.
