Islam is simple; so, you don’t need to be overly rigid about this issue. All that you need to do is to take water and gargle it three times. The Prophet (peace be upon him) demonstrated wudu’ to his companions: while doing so we are told: He scooped water with his hands and gargled with it three times.

 

The Prophet’s companions remind us that he was the most compassionate teacher; who never omitted to teach us anything we ought to practice in our religion. He also warned against rigidity and hair-splitting: ‘Leave this religion as I have left it; people before you perished because of their indulgence in hair-splitting questions and departure from the (straightforward and natural) way of their Prophets.

Almighty Allah knows best.
