Anas bin Malik reported,

The Prophet ﷺ said, "Maintain proper balance in prostration, and let none of you stretch out his forearms like a dog. When one of you needs to spit, let him not spit in front of himself nor to his right, for he is in private conversation with his Lord."

حدثنا حفص بن عمر قال حدثنا يزيد بن إبراهيم قال حدثنا قتادة

عن أنس بن مالك

عن النبي ﷺ قال اعتدلوا في السجود ولا يبسط ذراعيه كالكلب وإذا بزق فلا يبزقن بين يديه ولا عن يمينه فإنه يناجي ربه
