The best Provision during Hajj is Thaqwa 

السلام عليكم ورحمة الله وبركاتة

بِسْمِ ٱللَّٰهِ ٱلرَّحْمَٰنِٱلرَّحِيمِ 

Quran:

Ḥajj is [during] well-known months, so whoever has made ḥajj obligatory upon himself therein [by entering the state of iḥrām], there is [to be for him] no sexual relations and no disobedience and no disputing during ḥajj. And whatever good you do - Allāh knows it. And take provisions, but indeed, the best provision is fear of Allāh. And fear Me, O men of understanding. [2:197].

Narrated Ibn `Abbas: The people of Yemen used to come for Hajj and used not to bring enough provisions with them and used to say that they depend on Allah. On their arrival in Makkah they used to beg the people, and so Allah revealed, "And take a provision (with you) for the journey, but the best provision is the fear of Allah." (2.197). [Sahih Bhukari, 1523]
