I am 30 years old, not good-looking, and I don't have a stable career. I don't wish to delay marriage and want to complete half my faith but most importantly I am in fear of falling into sin. What should I do?
You should try your best to get married with a suitable believer as soon as possible. Outer looking is not important nor financial situation as far as faith and morals are nice.
Marriage itself opens gates of income as we read in the Hadeeth: Get married for more income, surely marriage brings blessings in income. تزوّجوا للرزق فإن فيهن بركة.
Keep on repeating Salawaat and Istighfaar and reciting the verse: إنّ هذا لَرِزقُنا ما له مِن نَفاد Sura 38, verse 54.
Wassalam .
