The Messenger of Allah ﷺ would not pray in our wrappers or in our quilts. Ubaydullah said: My father (Mu'adh) doubted this.  

كَانَ رَسُولُ اللَّهِ ﷺ لاَ يُصَلِّي فِي شُعُرِنَا أَوْ فِي لُحُفِنَا قَالَ عُبَيْدُ اللَّهِ شَكَّ أَبِي  

The Prophet ﷺ would not in our quilts. Hammad said: I heard Sa'id b. Abi Sadaqah say: I asked Muhammad (b. Sirin) about it. He did not narrate it to me, but said: I heard it a long time ago and I do not know whom I heard it. I do not know whether I heard it from a trustworthy person or not. Make an inquiry about it.  

أَنَّ النَّبِيَّ ﷺ كَانَ لاَ يُصَلِّي فِي مَلاَحِفِنَا قَالَ حَمَّادٌ وَسَمِعْتُ سَعِيدَ بْنَ أَبِي صَدَقَةَ قَالَ سَأَلْتُ مُحَمَّدًا عَنْهُ فَلَمْ يُحَدِّثْنِي وَقَالَ سَمِعْتُهُ مُنْذُ زَمَانٍ وَلاَ أَدْرِي مِمَّنْ سَمِعْتُهُ وَلاَ أَدْرِي أَسَمِعْتُهُ مِنْ ثَبَتٍ أَوْ لاَ فَسَلُوا عَنْهُ
