Website: Call to Islam
Assalamu Alaikum.
Like audios?
Well, there’s loads of them on this site: http://www.calltoislam.com/
If you scroll down, you’ll see that they also have a “Preparation for Ramadan” section where they’ve mentioned all the related audios and texts. I’ve put up some of them on this blog but there are lots more left.
There’s lots of useful information on this site, masha-Allah, and they keep adding more stuff every week. Be sure to check it out.
