Sixteen wickets fell on the first day of the final Test as England slumped to 6-104 after skittling Pakistan for just 99 in Dubai.
Captain Andrew Strauss (41) and nightwatchman James Anderson (three) will resume at the crease on Saturday's second day after Alastair Cook (one), Jonathan Trott (two) and Ian Bell (five) fell cheaply.
Earlier, Stuart Broad (4-36) and Anderson (3-35) hustled Pakistan out to take the early advantage at the Dubai International Cricket Stadium, after Pakistan captain Misbah-ul-Haq won the toss and elected to bat.
Only Asad Shafiq offered resistance for Pakistan with 45 off 78 balls before he was trapped lbw by Monty Panesar.
Anderson took advantage of some early moisture to strike during the day's opening stages, trapping opener Taufiq Umar (0) for a duck.
Broad snared Azhar Ali (one) in his third over through a caught-behind, and accounted for Younis (four) in his next
The strike bowler then trapped Mohammad Hafeez (13) lbw, and Anderson dismissed Misbah (one) after a successful challenge to see the hosts slump to 5-21.
Panesar broke the longest stand, between Shafiq and Saeed Ajmal (12), trapping both men lbw four overs apart.
Umar Gul's last salvo added 13 runs before Anderson clean bowled him to wrap up the innings.
In reply, England got off to a horror start, losing Cook and Trott to Gul's incisive opening spell to be in trouble at 2-19 at tea.
Strauss and Kevin Pietersen combined convincingly with a 57-run third-wicket stand that wrestled back control for England.
Pietersen initially looked comfortable and was unlucky to be undone by a review lbw decision that adjudged Abdur Rehman's delivery to be just shaving off stump.
He was gone for 32 and there was an element of misfortune about Bell's dismissal soon after.
Undone by a Saeed Ajmal doosra, Bell overbalanced and the ball ricocheted off his gloves and the keeper's and onto the stumps.
Eoin Morgan suffered another failure, gone for 10 when trapped lbw by Rehman's orthodox spin, before Matt Prior (six) became the spinner's third victim of the day.
England will resume five runs ahead with four wickets remaining in their first innings.
