Silsilat al-Ahadith al-Sahihah

When Sayyiduna Abu Bakrah (may Allah be pleased with him) came, the Messenger of Allah (peace and blessings be upon him) was in the state of bowing (ruku‘). He performed ruku‘ before reaching the row and then walked and joined the row. When the Prophet (peace and blessings be upon him) completed the prayer, he said: “Who among you bowed before reaching the row and then walked and joined the row?” Abu Bakrah said: I did so. The Prophet (peace and blessings be upon him) said: “May Allah increase your eagerness, but do not do so again.”
