Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever makes such a gesture during prayer that can be understood, then that person must repeat his prayer." One of the narrators of this narration is unknown, and the last part of the narration is an addition to the narration; it is possible that these are the words of the narrator. It is authentically established from the Noble Prophet (peace and blessings be upon him) that he used to make gestures during prayer. This hadith has been narrated from the Noble Prophet (peace and blessings be upon him) by Sayyiduna Anas, Sayyiduna Jabir (may Allah be pleased with them), and other noble companions (may Allah be pleased with them). Shaykh Abul Hasan (i.e., Imam Daraqutni, may Allah have mercy on him) says: This narration has also been narrated by Sayyiduna Abdullah bin Umar and Sayyidah Aisha (may Allah be pleased with them).
