Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world. — James 1:22,27

Dalili da aka ba aka ba da sassan yankunan da suka dace wanda masu sayarwa za su iya amfani da su don gudanar da bincike da gwada gwagwarmayar fasahar su da kuma inganta sakon su don sake tabbatar da masu amfani.
