[Machine] The Messenger of Allah ﷺ used to pray while carrying Umaamah, the daughter of Zainab, the daughter of the Messenger of Allah ﷺ , and the daughter of Abu Al-As ibn Rabee'ah ibn Abd Shams. When he stood up, he carried her, and when he prostrated, he put her down. Yahya said: Yes, this is the wording of the hadith of Yahya ibn Yahya.  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُصَلِّي وَهُوَ حَامِلٌ أُمَامَةَ بِنْتَ زَيْنَبَ بِنْتِ رَسُولِ اللهِ ﷺ وَلِأَبِي الْعَاصِ بْنِ رَبِيعَةَ بْنِ عَبْدِ شَمْسٍ فَإِذَا قَامَ حَمَلَهَا وَإِذَا سَجَدَ وَضَعَهَا قَالَ يَحْيَى قَالَ نَعَمْ لَفْظُ حَدِيثِ يَحْيَى بْنِ يَحْيَى  

I was in the company of the Messenger of Allah ﷺ on a journey when he said: Mughira take hold of this jar (of water). I took hold of it and I went out with him. (I stopped but) the Messenger of Allah ﷺ proceeded on till he was out of my sight. He relieved himself and then came back and he was wearing a tight-sleeved Syrian gown. He tried to get his forearms out. but the sleeve of the gown was very narrow, so he brought his hands out from under the gown. I poured water over (his hands) and he performed ablution for prayer, then wiped over his socks and prayed. (Using translation from Muslim 274d)   

كُنْتُ مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَقَالَ يَا مُغِيرَةُ خُذِ الْإِدَاوَةَ فَأَخَذْتُهَا ثُمَّ خَرَجْتُ مَعَهُ فَانْطَلَقَ رَسُولُ اللهِ ﷺ حَتَّى تَوَارَى عَنِّي فَقَضَى حَاجَتَهُ وَعَلَيْهِ جُبَّةٌ شَامِيَّةٌ ضَيِّقَةُ الْكُمَّيْنِ فَذَهَبَ لِيُخْرِجَ يَدَهُ مِنْ تَحْتِ كُمِّهَا فَضَاقَتْ فَأَخْرَجَ يَدَهُ مِنْ أَسْفَلِهَا فَصَبَبْتُ عَلَيْهَا فَتَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ مَسَحَ عَلَى خُفَّيْهِ ثُمَّ صَلَّى  

[Machine] There is no harm in praying in the clothing of Jews and Christians.  

لَا بَأْسَ بِالصَّلَاةِ فِي رِدَاءِ الْيَهُودِ وَالنَّصَارَى
