A woman has built a mosque after thirty years of saving her late husband's retirement salary.

The story was shared on Twitter by her son Mohammad Al Harbi who tweeted a picture of his mother in the mosque saying, "How great are you, mother... she never enjoyed my late father's modest retirement salary.

"She spent 30 years saving it up one riyal at a time until she built a mosque in my father's name.

"May he rest in peace and be granted a place in heaven. We belong to God and to him we return."
