Is it necessary for the head of the deceased to be on the imam's right when praying over him?

The questioner : The first question we present to the Honorable Shaykh (may Allah preserve him and grant him scrupulousness). The questioner says: You have just prayed over the funerals, and you placed the heads of the deceased on the left, whereas we know that the head of the deceased is to be on the right. We have not seen anyone until now who prayed except in the manner we know, so please inform us of the correct ruling. May Allah reward you with good.

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful. The correct position is that I did not know, I was not aware until this day, that in the Sunnah it is necessary for the deceased to be on his right.

The questioner : No, and we do not see any of the scholars saying that either, but this is something the people have grown accustomed to, so from which

The Shaykh : Because the people, or many of them, believe that it is obligatory for the head to be on the right. I instructed the brothers who brought the two deceased a little while ago to place the head on the left, so that it becomes clear that the matter is broad, and that it is all equal. However, in the grave, the face of the deceased must be toward the qiblah. And it is better for him to be on his right side, like a sleeping person, because the Prophet (peace and blessings be upon him) ordered al-Bara' ibn 'Azib, when he wanted to sleep, to sleep on his right side, and sleep is a minor death. So the scholars said, therefore, the deceased is placed in his grave on his right side facing the qiblah. And if he is placed on his left side facing the qiblah, there is no harm, but it is leaving the practice of the Companions and the Sunnah.
