In the morning, I did not know that I had ihtilam at night and so went to masjid for Fajr salah and was there in masjid for nearly 2 hours. Afterwards I came to home and went to bathroom and saw that I had marks on underwear and found that I had ihtilam. I did salah and did taleem in masjid. Now what should I do? (1) Should I do qaza of Fajr? (2) Is there any kaffarah for it? (3) What should I do now? Please help me.
بسم الله الرحمن الرحيم
In the above mentioned case, you should reoffer your Fajr salah and there is no financial kaffarah. You should take care in future and also do taubah and istighfar.
Allah knows Best!
