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 فَأَكَلَ مِنْهُ ثُمَّ قَالَ رَسُولُ اللهِ ﷺ قُومُوا فَلَأُصَلِّ لَكُمْ قَالَ أَنَسٌ فَقُمْتُ إِلَى حَصِيرٍ لَنَا قَدِ اسْوَدَّ مِنْ طُولِ مَا لُبِسَ فَنَضَحْتُهُ بِمَاءٍ فَقَامَ عَلَيْهِ رَسُولُ اللهِ ﷺ فَقُمْتُ أَنَا وَالْيَتِيمُ وَرَاءَهُ وَقَامَتِ الْعَجُوزُ مِنْ وَرَائِنَا فَصَلَّى بِنَا رَسُولُ اللهِ ﷺ رَكْعَتَيْنِ ثُمَّ انْصَرَفَ
