Verses of Holy Quran

وَلِلَّهِ عَلَى النَّاسِ حِجُّ الْبَيْتِ مَنِ اسْتَطَاعَ إِلَيْهِ سَبِيلًاوَمَن كَفَرَ فَإِنَّ اللَّهَ غَنِيٌّ عَنِ الْعَالَمِين َ

And Pilgrimage to the House is incumbent upon men for the sake of Allah, (upon) every one who is able to undertake the journey to it; and whoever disbelieves, then surely Allah is Self-sufficient, above any need of the worlds. (Aal-e-Imran, Chapter #3, Verse # 97)

وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ 

And complete the Hajj or Umrah in the service of Allah
(Al-Baqara, Chapter #2, Verse # 196)
