the prophet peace be upon him, said meaning indeed a slave speaks a word which pleases Allah, but he doesn’t think much of it. Allah elevates him by degrees, and indeed a slave speaks a word which angers Allah and we seek refuge in Allah from His anger. Ameen
And he does not think much of it, but he will be sent into hellfire because of it and we seek refuge in Allah from hellfire and we seek refuge in Allah from speaking something which may cause us to enter hellfire. Ameen
