It (a thing, or an affair, or event, TA) induced, or excited, him to wonder. (K, TA. [See also 2.]) In the following saying of Ibn- Keys-er-Rukeiyát,
the meaning is, [She saw upon my head some hoariness, which I did not hide; and she said to me, “ Is this Ibn-Keys? ” somewhat of hoariness] causing her to have wonder. (TA.)رَأَتْ فِى الرَّأْسِ مِنِّى شَيْبَةً لَسْتُ أُغَيِّبُهَافَقَالَتْ لِى ابْنُ قَيْسٍ ذَا وَبَعْضُ الشَّيْبِ يُعْجِبُهَا

And It (a thing, or an affair, or event, TA) induced in him wonder, or admiration, and pleasure, or joy: (K:) or it excited his admiration, or approval: (Msb:) or it pleased, or rejoiced, him. (TA.) You say, أَعْجَبَنِى هٰذَا الشَّىْءُ لِحُسْنِهِ [This thing has excited my admiration, or approval, or has pleased me, for its goodness, or goodliness, or beauty]. (S, O.) And أَعْجَبَنِى حُسْنُهُ [Its goodness, or goodliness, or beauty, excited my admiration, &c.]. (Msb.)

And أُعْجِبَ بِهِ
He was excited to wonder, or admiration, and pleasure, or joy, by it; he admired it, and was pleased with it, or rejoiced by it. (K.) You say, أُعْجِبَ
بِنَفْسِهِ, (S, O, Msb,) verbal noun إِعْجَابٌ, [which is often used as synonym with عُجْبٌ, the corresponding subst.,] (O,) [He admired himself, (lit. was excited to admiration by himself,) was pleased with himself, or was self-conceited, or vain; or] he exalted, and magnified, himself; was haughty, and proud. (Msb.)

[مَا أَعْجَبَهُ generally signifies How wonderful is it!]
5.
مَا أَعْجَبَهُ بِرَأْيِهِ [How greatly does he admire his opinion or judgment! or how greatly is he pleased with it! or how conceited, or vain, or proud, is he of it!] is anomalous [in two respects], (S, O, K,) not to be taken as an example to be imitated; (S, O;) for the verb here is formed from a passive [and augmented] verb [أُعْجِبَ], like as is the case in مَا أَشْغَلَهُ; whereas it is the primary rule with respect to the verb of wonder that it shall not be formed from any but an active [and unaugmented] verb. (TA.)
