The tour will now take place "as soon as it is reasonably possible", Pakistan Cricket Board (PCB) confirmed in a media release on Friday (February 14).
South Africa were slated to tour Pakistan in late March for a three-match T20 series in Rawalpindi.
South Africa will not be touring Pakistan in the proposed one-week window from March 22-29 to manage players' workload.
"This has been done purely because of the heavy workload and worldwide schedule our players are facing in the immediate future", said Faul. Furthermore, the Pakistan Cricket Board (PCB) meant to make them stay back in Dubai and board them the flight to Pakistan for the T20I leg of the tour, in Rawalpindi.
Pakistan successfully hosted two tests against Sri Lanka in December - their first at home since a militant attack on Sri Lanka's team bus in Lahore in 2009 that left six security personnel and two civilians dead and six players hurt.
South Africa are now hosting England for a T20I series, which was preceded by four Tests and three ODIs. The visitors clinched both the ODI as well as the Test series. "We will now work together to find an appropriate window in the global cricket calendar", concluded Faul.
PCB CEO Wasim Khan said that the CSA's decision based on the player workload was "understandable", and added that the two boards will reschedule the tour at a later date.
South Africa's tour to Pakistan did face logistical challenges, and CSA was planning to send a security delegation to Pakistan next month during the PSL to assess the situation. "We're pleased CSA remains committed to rescheduling this short series as soon as practically possible".
