It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) prayed while he (peace and blessings be upon him) was carrying Umamah bint Abi al-As bin al-Rabi'. When he bowed, he would put her down, and when he stood up, he would pick her up.
