(S, IB, Msb, K, * TA.) b2:  [Hence,] جَدَا عَلَيْهِ شُؤْمَهُ (assumed tropical:)  He drew his evil fortune, or ill luck, upon him: an ironical expression; [for it literally means he gave him, or bestowed upon him, his evil fortune.] (TA.) b3:  Hence also, عَلَيْكَ ↓ اجدى (tropical:)  It (a thing) sufficed thee. (Msb.) فِعْلُهُ شَيْئًا ↓ مَا أَجْدَى (tropical:)  His deed, or act, did not profit him, or avail him, aught. (Msb.) And عَنْكَ هٰذَا ↓ مَا يُجْدِى (assumed tropical:)  This does not stand thee in any stead; does not profit thee, or avail thee. (S.) A2:  جَدَوْتُهُ, (S, IB, Msb, K, *) [aor. ـُ inf. n. جَدْوٌ; (K;) and جَدَيْتُهُ; (K in art. جدى;) and ↓ اِجْتَدَيْتُهُ, (S, Msb, K, *) and ↓ اِسْتَجْدَيْتُهُ; I sought, or demanded, (S,) or asked, (IB, Msb, K,) of him (S, IB, Msb, K) a gift, (S,) or a thing wanted. (K.) [See an ex. of the last of these verbs in a verse cited in art. تا.] Hence, مُجَادَاةٌ [inf. n. of ↓ جادى]: whence, in a trad., وَقَدْ عَرَفُوا أَنَّهُ لَيْسَ عِنْدَ مَرْوَانَ مَالٌ يُجَادُونَهُ عَلَيْهِ, meaning يَسْأَلُونَهُ عَلَيْهِ [i. e. And they knew that there was not, in the possession of Marwán, property for which they should ask as owed by him]. (TA.) 3 جَاْدَوَ see 1.4 أَجْدَوَ see 1, in five places.A2:  Also اجدى, He obtained a gift.

(K.) One says also سَمَآءٌ جَدًا, meaning A rain having a rain following it; making the latter word masc. because it has the force of an inf. n. (TA.) And اَلّٰهُمَّ اسْقِنَا غَدَقًا وَجَدًا طَبَقًا [O God, water us with a copious rain, and a rain that shall cover the land]: (S, TA:) occurring in a trad. respecting prayer for rain. (TA.) b3:  and خَيْرٌ جَدًا Ample good; (K;) of wide extent to men. (TA.) A2:  لَا آتِيكَ جَدَا الدَّهْرِ (S, * K, * TA) i. e. [I will not come to thee] ever, like يَدَ الدَّهْرِ; (S, TA;) or to the end of time. (K, TA.) جَدْوَى A gift; (S, Msb, K;) as also ↓ جَدًا: (S, K:) dual (of the former, TA) جَدْوَانِ and جَدْيَانِ; (Lh, M, K;) the former, regular; (M, TA;) the latter, anomalous, (M, K, TA,) formed by commutation. (M, TA.) You say, مَا أَصَبْتُ مِنْ فُلَانٍ جَدْوَى قَطُّ [I have not obtained from such a one a gift ever]. (TA.) And hence the prov., شَغَلَتْ شِعَابِى  جَدْوَاىBَ: see art. شعب. (S in that art.) b2:  See also جَدًا.جَدَآءٌ  profit, utility, or avail. (S, TA.) So in the saying,  فُلَانٌ قَلِيلُ الجَدَآءِ عَنْكَ  [Such a one is of little profit, utility, or avail, to thee; will stand thee in little stead]. (S.) جَدِىٌّ [originally جَدِيوٌ] Munificent, or bountiful. (TA.) جَادٍ Asking, seeking, or demanding, (S, K,) a bounty, or benefit, (S,) or gift: (K:) pl. جُدَاةٌ. (TA.) أَجْدَى [More, and most, profitable, useful, or availing]. It is said in a prov., أَجْدَى مِنَ الغَيْثِ فِى أَوَانِهِ [More profitable than rain in its season]. (Meyd.)
