( Considering this )
Laughter for a soliloquy slanders prestige and politeness, and a non-literate person does not solemnise. If he smiles, he is always smiling because of his Lord’s laughter in a calamity that occurs like the old woman of Moses, peace be upon him, and the story of Hanad. It is polite for the servant to smile in such calamities to laugh at the truth. If he is in a calamity that makes him smile, and he smiles, then he is ill-mannered and not fit to attend. He is prevented from attending, so he resumes repentance and work. He is in the same position as someone who says that smiling interrupts prayer.
