Questioner: What is more deserving, our Shaikh, when counting. Do you begin with the right hand or the left hand…?
Shaikh: Yes, of course you begin with the Sunnah
Questioner: With the right?
Shaikh: Yes. As for you starting with the left hand?
Questioner: [Like when counting] eleven or one hundred?
Shaikh: As for the left hand, then this is the way of the disbelievers
