The star's little cousin, whose image has been shared on social media by distraught yet hopeful relatives, enjoyed a special day out in July, when Zayn threw a funfair party for his fiancée Perrie Edwards on a Hertfordshire country estate as she celebrated turning 21.
On Wednesday, the star's cousin Aaroosa Malik posted a picture of Arshiya on Instagram, with the accompanying caption: 'Please can everyone pray for Arshiya as much as you can as her MRI scan didn't come out good. 'Doctors are saying theres nothing they can do & have put her on life support machines now. 'Please keep her in your duas always & the rest is up to Allah. '
In the early hours of Friday morning she tweeted: 'Went to see Arshiya today. Gutted me up! Looks like a totally different baby :( Please keep her in your duas [prayers]. Thank you' On Tuesday, Zayn's sister Doniya Malik tweeted: 'Thank you every1 hu did dua for arshiya things are looking good, but still need ur duas she had 1% chance! Jus shows there is a god.. (sic)' She added: 'And prayers work xxx'
Arshiya, of Bradford, went in for surgery on Monday, while her famous older cousin was a whole ocean away with his 1D bandmates on their Where We Are tour. The stars are due to play at the Gillette Stadium in Boston, Massachusetts, for the second night in a row on Friday. They will then go on to Washington, DC, for a show at the Nationals Park on Monday.
My prayers go out to Zayn and his family :(
