A Saudi woman is going viral all over Twitter after saving up her late husband's retirement salary for 30 years and using the money to build a mosque. 

The wife's story went viral on social media after her son, Mohammad Al Harbi, tweeted about it on Monday. 

In his tweet, the man posted a picture of his mother standing on the premises of the newly built place of worship, which is a tribute to his father. 

Just hours after it was first uploaded, the tweet started widely circulating online and continues to make the rounds on Twitter. 

It all started when Al Harbi tweeted out his mother's story

"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." 

And it broke Saudi Twitter

People loved it

"The greatness of a wife"

"If I had enough money... I would've given her back all that she spent on building the mosque"

"Mashallah"

"Love in its greatest form"

"This is the definition of loyalty"

Many hailed the wife and mother

"She's a great person."

"May God unite them in the afterlife"
