What may not be done during Prayer and what is permitted - Section 1
وَعَن أبي قَتَادَة قَالَتْ: رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَؤُمُّ النَّاسَ وَأُمَامَةُ بِنْتُ أَبِي الْعَاصِ عَلَى عَاتِقِهِ فَإِذَا رَكَعَ وَضَعَهَا وَإِذَا رَفَعَ مِنَ السُّجُودِ أَعَادَهَا "
Abu Qatada said: I saw the Prophet (ﷺ) leading the people in prayer with Umama daughter of Abul ‘As on his shoulder. When he bowed he put her down, and when he got up after the prostration he put her back. (Bukhari and Muslim.)
