"Be moderate in bowing and prostration, and do not rest your forearms along the ground like a dog."
Sunan an-Nasa'i Book 11, Hadith 153
← Previous Hadith "The Messenger of Allah (ﷺ) said: 'The prayer is not valid if a man does not bring his backbone to rest while bowing and prostrating.'"

Sunan an-Nasa'i Book 11, Hadith 152 Next Hadith → They were with 'Abdullah in his house and he said: "Have these people prayed?" We said: "Yes." So he led them in prayer and stood between them, with no Adhan and no Iqamah, and said: "If you are three then do this, and if you are more than that then let one of you lead the others in prayer, and let him lay his hands on his thighs. It is as if I can see the fingers of the Messenger of Allah (ﷺ), interlaced.'"
