The letter came out as part of a trove of documents related to the late Al Qaeda leader the US government released on Wednesday.
Bin Laden wrote:
My will: If I get killed, and you want to return to your family, then that is okay, but you have to raise my children properly, and to watch them, and be careful of bad company for them, especially after puberty, especially the girls `Asma` and (TN: possibly, Duha). So be very careful about them and if you can marry them to mujahidin, then that is best, or else to good people.
Here's the full letter, which also includes a note to bin Laden's father:
Osama bin Laden Letter to Wife
Bin Laden had more than one wife, and it's unclear to whom this letter was directed.
A team of US Navy SEALs killed bin Laden in 2011 in his hideout in Abbottabad, Pakistan.
