The family feared the worst when a Taliban offensive brought fighting towards their home. They left when they heard gunshots.
“We couldn’t take any of our belongings, we left only with our lives,” added Shafiqa.
The family belongs to the Shia Hazara ethnic group, who were singled out by the Sunni Taliban during their November operation in Ghazni.
The UN said up to 4,000 families fled, with witnesses describing scenes of “absolute terror” to AFP.
Shafiqa said she hid her famous son’s face with a scarf to prevent him from being recognised as they fled.
They took refuge first in a mosque in Bamiyan, before arriving in Kabul six days later. Among their belongings left behind are the football and the jersey signed by Messi.
Although Afghan security forces have beaten back the Taliban in Jaghori, the family says it no longer feels safe.
“The danger of the Taliban coming back is high, going back is not an option,” Shafiqa said.
The family have already fled once before, to Pakistan in 2016, where they sought asylum in “any safe country”.
They returned reluctantly to Jaghori after their money ran out, she said.
Murtaza’s father Arif remains in Jaghori working as a farmer while his family lives in Kabul.
