Walayah

Welayah or Walaya (Arabic: وَلاية, meaning "guardianship" or "governance") is a general concept of the Islamic faith and a key word in Shia Islam that refers, among other things, to the nature and function of the Imamate.

Welayah is something that can be granted to a person, community, or country that confers authority/guardianship to the wali (a person who has welayah) that they can exercise on behalf of someone else. For example, in fiqh, a father is wali of his children. The term wali holds a special importance in Islamic spiritual life and it is used with various meanings that relate to its different functions, including:

In Islam, the phrase ولي الله walīyu l-Lāh can denote one vested with the "authority of God":

إِنَّمَا وَلِيُّكُمُ اللّهُ وَرَسُولُهُ وَالَّذِينَ آمَنُواْ الَّذِينَ يُقِيمُونَ الصَّلاَةَ وَيُؤْتُونَ الزَّكَاةَ وَهُمْ رَاكِعُونَ
"Only God is your wali and his messenger and those who believe, establish worship, and pay the poor due while bowing down (in prayer)."^{[Quran 5:55]}
