Musannaf Ibn Abi Shaybah 8574 — Are bowing and prostration better

Salim bin Abi al-Ja'd said: A man came to Sayyiduna Abu Dharr (may Allah be pleased with him) and asked: "Where is Abu Dharr?" The people said: "He is at the foot of that mountain with his small flock." (The man said:) I came to him and he was praying. He was keeping the standing short and making many bowings and prostrations. When he had finished praying, I said: "O Abu Dharr! I saw you keeping the standing short in prayer and making many bowings and prostrations; what is the reason for this?" He said: "I have been told that whenever a Muslim makes a single prostration to Allah, Allah Almighty raises him one degree by it and wipes away one sin from him by it."
