Wrapping up her three-day official visit, Khar along with Foreign Secretary Salman Bashir and other members of the delegation spent over 30 minutes at the dargah in Nizamuddin in south Delhi.
Dressed in a salwar kameez, the 34-year-old Foreign Minister was accorded a traditional welcome by the office bearers of the dargah and was taken to Amir Khusro's grave where she offered a chadar.
Khar, who arrived here on Tuesday for talks with her counterpart S M Krishna, spent a few minutes there before proceeding to the shrine of Sufi saint Nizamuddin Auliya.
Since women are not allowed inside the shrine, she touched the chadar with her hand and gave it to other members of the delegation and office bearers who went inside and placed it.
Khar, the youngest Pakistani Foreign Minister, then offered prayers at the mosque adjoining the dargah where the priests asked her to pray for "peace between India and Pakistan."
"She prayed for peace between India and Pakistan and also for improvement of ties between the two countries. She was taken around the dargah by our nizamis and finally she also offered namaz," Diwan Syed Tahir Nizami, one of the office bearers of the dargah, told PTI.
He said they also prayed that Khar's purpose of the visit should be successful and "there should only be love" between the people of India and Pakistan.
High-profile visitors to India visiting devotional spots and devoted their prayers are not something new. During his India tour, French President Nicolas Sarkozy, coupled with his wife Carla Bruni, visited the tomb of Sheikh Salim Chishti (Fatehpur, Agra) and asked to be blessed with a child.
The miracle of praying in 16th century shrine didn't let her down. The former super model was expecting her first baby with Sarkozy, within days of completing her India tour.
