It is narrated from Hazrat Anas (may Allah be pleased with him) that once the prayer had been established and a man came quickly, his breath was heavy, and upon reaching the row he said, "Alhamdulillah hamdan katheeran tayyiban mubaarakan feehi." When the Prophet (peace and blessings be upon him) finished the prayer, he asked, "Who among you spoke?" He had said a good thing. So that man said, "O Messenger of Allah (peace and blessings be upon him)! I spoke. I was coming quickly and when I reached near the row, I said this phrase." The Prophet (peace and blessings be upon him) said, "I saw twelve angels rushing towards it to see who would raise this phrase first. Then they did not understand how much reward to write for it, so they asked Allah Almighty. Allah Almighty said, 'Write these words as My servant has said them.'"
