However, Jahan's son and Union Minister for New and Renewable Energy, Farooq Abdullah, was not present at the prayer meeting as he is in Mongolia to attend the oath-taking ceremony of Mongolian President Tsakhia Elbegdorj.
Omar visited the Naseembagh grave of Jahan, popularly known as "Madre-e-Meharban", near Hazratbal shrine on the banks of the Dal Lake, and offered 'Fateh' or special prayers.
He laid a wreath on his grandmother's grave and also on that of his grandfather, Sheikh Abdullah, affectionately known as Sher-i-Kashmir.
A large number of people, including ministers, legislators and political activists attended the prayer meeting.
