Is it correct way of marketing?

Our editorial team came across this marketing ploy by Rock Grills Restaurant .  We are not sure whether it is the right marketing strategy. The owner is not a Muslim. I have met the owner.

The person in charge of Rock Grills Restaurant Facebook Page shared the following from LavaStone Steakhouse on 2 October 2015. LavaStone Steakhouse is not certified Halal by MUIS.

Rock Grills Restaurant  is certified Halal by MUIS.

He mentioned that he can see the word ‘Allah’ on his steak. See below.

He also commented with the word ‘Allah’.

We are not sure whether this marketing strategy is correct. In the name of business, is the owner taking advantage of a faith?
