Get up, I shall lead you in prayer. Anas said: I got up and took a mat which had become black on account of long use. I then washed it with water. The Messenger of Allah ﷺ stood upon it. I and the orphan (Ibn Abi Dumairah, the freed slave of the prophet) stood in a row behind him. The old women stood behind us. He then led us in two raka'at of prayer and left. (Using translation from Abū Dāʾūd 612)   

أَنَّ جَدَّتَهُ مُلَيْكَةَ دَعَتْ رَسُولَ اللهِ ﷺ لِطَعَامٍ صَنَعَتْهُ لَهُ فَأَكَلَ مِنْهُ ثُمَّ قَالَ قُومُوا فَأُصَلِّيَ بِكُمْ قَالَ أَنَسٌ فَقُمْتُ إِلَى حَصِيرٍ لَنَا قَدِ اسْوَدَّ مِنْ طُولِ مَا لُبِسَ فَنَضَحْتُهُ بِمَاءٍ فَقَامَ عَلَيْهِ رَسُولُ اللهِ ﷺ وَصَفَفْتُ أَنَا وَالْيَتِيمُ وَرَاءَهُ وَالْعَجُوزُ مِنْ وَرَائِنَا فَصَلَّى لَنَا رَكْعَتَيْنِ ثُمَّ انْصَرَفَ
