אבן העזר נ״חEven HaEzer 58

Se’if 1א׳

צִוּוּ חֲכָמִים שֶׁיִּתֵּן אָדָם מִנְּכָסָיו מְעַט לְבִתּוֹ, וְזֶהוּ הַנִּקְרָא "פַּרְנָסָה". הַמַּשִּׂיא אֶת בִּתּוֹ סְתָם, לֹא יִפְחֹת לָהּ מִכְּסוּת שֶׁפּוֹסְקִין לְאֵשֶׁת עָנִי שֶׁבְּיִשְׂרָאֵל. בַּמֶּה דְבָרִים אֲמוּרִים, שֶׁהָיָה הָאָב עָנִי; אֲבָל אִם הָיָה עָשִׁיר, הֲרֵי זֶה רָאוּי לִתֵּן לָהּ כְּפִי עָשְׁרוֹ:

The Sages commanded that one must give a small part of his property to his daughter, and this is call "parnasa" (that is, livelihood). One who marries off his daughter without any stipulations, he may not give her anything less than [simple] clothing that is given to the wife of a poor Israelite. When does this apply? When the father [himself] is poor. However, if he is wealthy, then it is ideal that he gives to her according to his wealth.

Se’if 2ב׳

הִתְנָה עִם הֶחָתָן לְהַכְנִיסָהּ לוֹ עֲרֻמָּה, לֹא יֹאמַר: לִכְשֶׁתָּבוֹא לְבֵיתִי, אֲכַסֶנָּה, אֶלָּא מְכַסֶה אוֹתָהּ וְעוֹדָהּ בְּבֵית אָבִיהָ:

If [the father] stipulates with the groomsman to marry her naked [that is, without the father providing her with clothing], [the groomsman] may not say: "When she comes into my house, I will clothe her." Rather, he must clothe her while she is still living in her father's house.
