Hence other things are thus termed by way of comparison. (S.) It is said in a tradition (S, M) of 'Áïsheh, (M,) كَانَ عَمَلُهُ دِيمَةً (S, M, Msb) (assumed tropical:) His work was incessant [but moderate, or not excessive]; (Msb;) referring to Mohammad; (T, S, M, Msb;) on her being asked if he preferred some days to others: (T:) she likened it to the rain termed ديمة in respect of continuance and moderation. (T, M.) And it is related of Hudheyfeh that he said, mentioning فِتَن [i. e. trials, or probations, or conflicts and factions, &c.], إِنَّهَا لَاتِيَتُكُمْ دِيمًا دِيمًا, meaning (assumed tropical:) [Verily they are coming to you] filling the earth, or land, [and] with continuance. (T.)
