She wanted to donate a certain sum to contribute to the construction of a Masjid but her father advised her not to donate all the sum
I have a married daughter that entrusted me with keeping her Mahr (mandatory gift to a bride from her groom), which is 6000 riyals. Upon visiting her, she told me that she wished to donate her Mahr to build a Masjid (mosque). I felt sorry for her, lest she should give this large sum in charity and told her that it is enough to give 1000 riyals as charity. Since then, she has not spoken to me as if she is angry with me for objecting to her contribution of the entire amount to the Masjid. My question is: Did I commit a sin when I did not agree to the donation of the whole sum to the Masjid? Should I carry out her wish, even if this decreased her money? Please, advise. May Allah reward you with the best! As-salamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!)
Charity and donation that a daughter may give to the extension of a Masjid is a good and Mustahab (desirable) deed, but obeying one's father is a duty. The father did not prevent her from donating, but merely wanted her to reduce the contribution in pursuit of her interest. The father is then not to blame, but it is better to carry out her desire, for the great reward and goodness, hoping that Allah will give her greater compensation. Allah (Glorified be He) states:
And whatever good you send before you for yourselves, (i.e. Nawâfil non-obligatory acts of worship: prayers, charity, fasting, Hajj and ‘Umrah), you will certainly find it with Allâh, better and greater in reward.
(Part No. 8; Page No. 293) Allah (Glorified be He) also states:
...and whatsoever you spend of anything (in Allâh’s Cause), He will replace it. And He is the Best of providers.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
