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.  

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