Sayyiduna Abu Qatadah (may Allah be pleased with him) said: We were sitting in the mosque waiting for the prayer when the Messenger of Allah (peace and blessings be upon him) came out to us, and on his (peace and blessings be upon him) shoulder was his (peace and blessings be upon him) granddaughter Umamah bint Abi al-As bin al-Rabi', whose mother was Zaynab. He (peace and blessings be upon him) was saying the takbir while carrying her on his shoulder, and she was on his (peace and blessings be upon him) shoulder. When he bowed, he would put her down on the ground, and when he stood, he would lift her onto his shoulder again, until he completed the prayer, and he (peace and blessings be upon him) kept doing this.
