Narrated Anas bin Malik:
My grandmother Mulaika invited Allah’s Apostle for a meal which she had prepared specially for
him. He ate some of it and said, “Get up. I shall lead you in the prayer.” I brought a mat that had be –
come black owing to excessive use and I sprinkled water on it. Allah’s Apostle stood on it and prayed
two Rakat; and the orphan was with me (in the first row), and the old lady stood behind us.
