Sayyiduna Abu Qatadah (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) leading the people in prayer while Umamah bint Abi al-As bin al-Rabi' was on his (peace and blessings be upon him) shoulder. When he (peace and blessings be upon him) bowed, he would put her down, and when he raised his head from prostration, he would pick her up again.
