شَأَنْتُ شَأْنَهُ

i. q. قَصَدْتُ قَصْدَهُ [meaning I pursued his (another's) way, or course, doing as he did]; (S, L, K: * in the K, شَأَنَ شَأْنَهُ and قَصَدَ قَصْدَهُ;) and in like manner one says, شَأْنَهُ ↓ اشتأن. (K.)

And اِشْأَنْ شَأْنَكَ Do thou what thou dost well. (S, L, K. *) And Keep thou to thy affair. (IAar, L.)

And مَا شَأَنَ شَأْنَهُ He did not know, or had not knowledge of, him, or his affair or case or state: (Lh, IAar, L, K:) [from a passage in the L, imperfectly written, it seems, according to Lh, to be said of one who does what another likes or dislikes, apparently without regard to his liking it or disliking it, agreeably with what here follows:] or (K) this means, (S, K,) or means also, (L,) he did not care for, mind, heed, or regard, him. (S, L, K. [In the S and L, the verb in the sense thus explained is in the first pers.: and in one place in the L it is explained by أَرَادَ, which often has this meaning.]) One says also, لَأَشْأَننَّ شَأْنَهُمْ, meaning I will assuredly know, or try, prove, or test, (لَأَخْبُرَنَّ,) their affair or case or state: (L:) or this means I will assuredly corrupt, or pervert, or mar, their affair or case or state: (S, L, K: *) and لَأَشْأَنَنَّ خَبَرَهُ, (L,) or خَبَرَهُمْ, (K,) means I will assuredly know, or try, prove, or test, [his, or their, state, or] him, or them. (L, K. [In the CK and in my MS. copy of the K, لَاُخْبِرَنَّهُمْ, is erroneously put for لَأَخْبُرَنَّهُمْ.])

-A2- شَأَنَ بَعْدَكَ means صَارَ لَهُ شَأْنٌ [i. e., apparently, He became a person to whom importance attached (according to the general meaning of لَهُ شَأْنٌ) after thou knewest, or sawest, or mettest, him; بَعْدَكَ being for بَعْدَ عَهْدِكَ بِهِ, agreeably with common usage]. (K.)
