Answer
(Fatwa: 1440/D=183/L/1430)
Abortion is a sin, especially with the intention you mentioned that your husband had no income to sustain; since it is clearly against the commandment of the Quran:
وَلا تَقْتُلُوا أَوْلادَكُمْ خَشْيَةَ إِمْلاقٍ نَحْنُ نَرْزُقُهُمْ وَإِيَّاكُمْ إِنَّ قَتْلَهُمْ كَانَ خِطْئًا كَبِيرًا
?And kill not Your Children for fear of poverty. We provide for them and for you, surely the killing of them is a great sin.? (17:31)
Therefore, you should do taubah and seek forgiveness from Allah with firm determination not to do the same in future. It is sin to abort for continuing education.
