Hadith 234
Sayyiduna Abu Qatadah (may Allah be pleased with him) says: The Prophet (peace and blessings of Allah be upon him) used to perform prayer while carrying Umamah bint Abi al-As ibn al-Rabi’, who was the daughter of Zaynab, the daughter of the Messenger of Allah (peace and blessings of Allah be upon him). When he would bow (ruku’), he would put her down, and when he stood up, he would pick her up again. This continued until he finished the prayer.
