It was recited to Sufyan while I was present. I heard Ibn ‘Ajlan and Ziyad ibn Sa‘d, from ‘Amir ibn ‘Abd Allah ibn al-Zubayr, from his father, who said: I saw the Prophet, peace and blessings be upon him, "supplicating like this," and Ibn al-Zubayr clasped (his hands).
It is narrated from Sayyiduna Ibn Zubair that when the Prophet (peace and blessings be upon him) sat in Tashahhud, he would place his right hand on his right thigh and his left hand on his left thigh, point with his index finger, and would not let his gaze go beyond that gesture.
